Introduction: Leather Briefcase

Picture of Leather Briefcase

For my birthday I wanted to buy a nice leather briefcase for myself. After shopping around I realized that with two teenage daughters at home, I wasn't prepared to spend $700-$1,000 on a luxury item just for me. I had this crazy thought; "I've made a few wallets, leather belts and holsters in my day. I should be able to make my own briefcase for 1/3 of the price!... Really, how bad could it be?" Well..... after $320 in materials, 6 months of free time invested, 14,300 saddle stitches done by hand, and finger tips so toughened that they wouldn't activate the screen on my iPhone.... I finally finished my present to ME! The reward is worth EVERY second spent working. The finished product is a hefty 11lbs, 4oz.... empty...... but is built to last several lifetimes.... Hey, no one ever said that looking cool doesn't come without a little effort... The project is not for the feint of heart, BUT IT IS NOT OVERLY DIFFICULT! YOU can do it! You need a plan, you need patience, and you need to keep the end vision in mind. It's kind of a long road, but it is strangely therapeutic. The perpetual bonus is that you can't go a week without someone pointing out how cool your briefcase is. The feeling of saying, "Thanks, I did it myself." is a feeling like no other. Try as you will, you just can't stop grinning.......

Follow along with me and I'll show you just how I ate this elephant one bite at a time...

Step 1: Materials & Tools

Step 2: Getting Started

OK, You've talked yourself into this odyssey now you need to do a few things before you dive into cutting and stitching:

USE YOUR BRAIN!

There are no patterns for this briefcase. I used the design elements of several different briefcases that I saw and liked on the internet. It's not rocket science; if you know the overall dimensions that you want everything kind of falls into place. For example; I wanted my briefcase to be 17" wide X 13" tall X 9" deep. Right away you know the front and center panels need to be 17" X 13", and I made the back panel/flap 17" X 24" to cover the back, and wrap around to the front. YOU are the creator, so you can size this to ANY dimension your heart desires!

PLAN AHEAD!!!

It would not hurt to make patterns specific to what you want (a step I should have done...) to help you lay out your cuts to get the most out of your side of leather. Remember you have to cut a few long strips for the wrap around straps, as well as the shoulder strap. Would stink to not plan ahead and wind up having to get ANOTHER side just to make your straps! Cut your straps first, then work your way down your list from the largest pieces to the smallest.

OCCUPY SOMEWHERE!

You're going to need some space to keep your "stuff" for this project so you don't have to keep moving it around... and you will likely occupy it until you're done....... so choose wisely.

Novice Tip: If you are limited on space and plan on occupying a corner of your dining room, it will save you heartache and thousands on counseling if you pre-emptively negotiate with your spouse BEFORE you get settled in and comfy...... just saying....

KEEP THE FAITH!!

It's a big project. If you get a little discouraged, hop on the web and look at other briefcases to inspire you and give you ideas.

Step 3: Belts & Shoulder Strap

Picture of Belts & Shoulder Strap

There is a method to this madness. By starting with the straps you accomplish THREE important feats.

1.) This insures the straps are cut first from the Kodiak side, so you will have all one piece lengths.

2.) My briefcase took 14,300 stiches by hand. You need to get good at it. About HALF of the stitches in this project live in the straps/pad/handle...... so what better place to start honing your stitching skills!

3.) If you get ticked off, lose interest and bail, at least you'll have a few belts to give away at Christmas!

Novice Tip: I used an old wooden jaw clamp to hold my straps while stitching because I was too cheap to buy a stitching pony.....and it made me feel smart. (See Photo)

Belts & Shoulder Strap:

I started with the two belts to wrap around the briefcase. My size was 1-1/2 wide by 45" long. You need two 45" long pieces of the Kodiak leather, and a 44" piece of nylon webbing. (The webbing is important as it adds stiffness to the strap, and does not allow the leather to stretch. The added bonus is that it gives the belt a padded look.)

-Spread a layer of the Barge cement on the flesh (fuzzy) side of one strap, and on one side of the cut nylon webbing. When they're tacky, stick them together.

-Now put the cement on the fuzzy side of the other piece, and on the other side of the nylon strap.

-When tacky, stick those together so you have two leather strips with the pretty side out and the nylon webbing sandwiched secretly in-between them.

-If you are in proximity to the kitchen, "borrow" a rolling pin and roll the strap out to make sure everything is sandwiched without air pockets.

-Set your stitching groover to 1/4" and run a groove around the outside of the whole strap. Then use your stitching wheel to mark your holes all the way around. THEN get your awl out and start stabbing away.

Novice Tip: Not necessary, but a HUGE help. I bought a $29 arbor press from harbor freight and installed a small "chuck" so I could put my awl needle in it. This was the best investment made and invaluable in punching the thousands of holes straight and even. I use this ALL of the time on projects. (See Photo)

-Start stitching! To get the basics on Saddle Stitching, refer to: "The Art of Hand Sewing - Al Stohlman

-When done, cut a slot for the buckle tongue, punch holes, and install the buckle securing the leather with Chicago Screws.

The Shoulder Strap is done the same way!!!!

Step 4: Shoulder Pad & Handle

Picture of Shoulder Pad & Handle

Shoulder Pad:

-I made a wood form the size of the pad that I wanted, then rounded the corners and edges with a sander.

-I wet a piece of the Kodiak leather and formed it over the wood, then let it dry. Then cut a piece of the 1/2" felt to the same dimensions of the wood form. Carefully round the edges with a razor blade.

-Cement the felt into the formed leather, then sew the backing piece on. (Don't forget the cut the slits so you can feed the strap through!)

Handle:

The handle was done by EXACTLY following the instructions in Al Stohlman's - "The Art of Making Leather Cases Vol 2". If you follow the instructions, the handles come out perfect every time.

Step 5: Front & Middle Panels

Picture of Front & Middle Panels

OK! If you've made it this far it's likely that the calluses on your fingers are hampering the screen performance on your Smart Phone...... but the upside is you can now cook chicken wings on the grill without using tongs.....

Time for some easy work.

-The front and middle panels are the same size. Cut them out of the Kodiak side to the length and height dimensions you want, then round the two bottom corners,

-Cut the Minelli glove leather to a size 1" larger all around.

-Apply your Barge Cement to the flesh side (fuzzy side) of each piece. When tacky CAREFULLY stick them together. Now is a good time to whip out that rolling pin you borrowed and flatten the heck out of it. NO BUBBLES!

-After you roll it, you can use your scissors and trim off the excess glove leather.

-Set your stitching groover to 1/2" and put a groove on the two sides and bottom (see photos.) You want to accent stitch the entire 1/2" groove.

-When you're done, set your groover to 1/4" and run a groove next to the one you just got done stitching. DON'T STITCH IT YET!

-I chose to add piping on the exposed ends that might come in contact with fingers. It is just a 1-1/8" strip folded over the edge and stitched. No extra work and gives it a good finished look.

Step 6: Center Divider Compartments

Picture of Center Divider Compartments

I chose to have a center divider to allow my briefcase have two compartments. On the front facing side of the divider I placed 4 compartments for cables, chargers and general briefcase treasures, On the back facing side of the divider I made a pocket for an iPad or Tablet.

Novice Tip: Depending on what you put on the divider take some time and THINK IT THROUGH! For mine, I had to sew everything at once because if I had sewn one side completely, I would have covered the area I needed to stitch for the other side. This resulted in stitching a little on the back...... then a little on the front..... then a little on the back..... Not difficult, but you have to think ahead!

Step 7: Center Assembly

Picture of Center Assembly

Lets make a briefcase!

OK, Time to start putting everything together to make a briefcase!

-Start from the center panel and work your way out.

-My briefcase was 9" thick, so each side panel strip was cut at 5" width (4.5" for the depth and an extra 1/2" to leave room for stitching.

-I also wanted outside pouches for a water bottle, and mini umbrella, so those pouches need to be included when stitching the panels to the center divider. Remember that THINK AHEAD advice???

Now is also the time to add the D-Ring for the shoulder strap. Super thick, and anchored with Chicago Screws.

Novice Tip - When using Chicago Screws, make sure you have a good fit and they are where you want them. When you're ready to permanently install, apply a drop of either Lock Tite, or clear fingernail polish on the threads before you tighten the screw. This will keep the screw from backing out.

Step 8: Time to Mock-Up

Picture of Time to Mock-Up

There comes a time in every project where you can't take it anymore and you need to SEE what it's going to look like!!!! Go ahead! You are ALMOST done! Indulge yourself and put the pieces together! Short pieces of scrap cut-off thread and office supply binder clips are your FRIENDS! Put it together, then just sit back for awhile and admire.... take a few pics... cry...... CELEBRATE!

Use this time to visualize the order in which you need to sew things together..... Then celebrate some more.

Step 9: Front Flap Assembly, Final Fit

Picture of Front Flap Assembly, Final Fit

We are getting closer, and it's actually starting to look like something!!!

Now it's time to install the back panel/flap. This piece is made the same as the front and center sections, it's just a bigger piece.

Back Panel/Flap

-Before you attach the flap to the whole assembly, it's easier to install your handle first. I apologize there is not an assembly picture of this, but if you look at the handle panel on the top, you will see that there are 4 Chicago Screws installed. These screws are attached to a 12" x 1" x 3/16" stainless steel bar on the inside of the flap (I just drilled 4 holes for the screws.) This bar is to help distribute the load when using the carrying handle. For the inside, I just rounded the corners and edges of the bar and covered it with Kodiak leather.

Final Fit

Here's where it will all come together. If you've done your job and everything is the size you want you will be in a happy place. Line up all of your holes and clip the panels into place with the binder clips. Then go back to your first hole and pull a scrap string through it and lightly tie it off. Do the same think about every 20 holes. This will lightly "tack" your panel on and keep everything in order as you stitch. Pull the scrap pieces out a stitch or two before you get to it and all will work out fine.

Novice Tip - When you are marking your stitching holes it is important to make sure your FIRST hole is where you want it on each piece. Because you are using a 6-Stitch per Inch wheel, ALL of your holes will line up (almost) perfectly. Keep in mind that in some places you may be going through SIX LAYERS of leather. With that said, if you use your friendly pliers you can stitch those panels into submission in no time.

Step 10: Don't Forget the D-Rings!!!

Picture of Don't Forget the D-Rings!!!

One of the things that gives this bag rugged looks are the big beefy Stainless Steel D-Rings on it. And there are a LOT on it. I count 12 total on my bag! The good news is that they are a piece of cake to put in. I used TWO different sizes. I used the 1-1/2" rings on the shoulder strap attachment points, and the center hang point by the handle, and 1-1/4" rings on everything else. You DO NOT need to install the rest on each corner if you don't like the look.

Simply cut a 4" strip of Kodiak leather, glue a 3-1/2" long piece of nylon webbing to the flesh side, put it through the ring, fold it in half and glue it together. As you are stitching on the front and back panels slide the leather flap on the d-ring to the position it looks best, mark the holes with your awl, pull the piece back out and make your final stitching holes. them line it up, and stitch it in. Once in, drill a hole between the stitch lines and install a Chicago Screw.

Step 11: The Little Details

Picture of The Little Details

Tablet Pocket Flap: I thought I needed a flap to cover my iPad, but it turns out this isn't really necessary. When the top is closed there is no way it will ever fall out. I would remove it, but since it's already stitched in I don't want the unsightly holes visible every time I open the briefcase. Lesson learned - Even though it looks cool, it may not be necessary......

Maker's Mark: I lucked out and had a friend with a 3D printer who made me a 1-1/2" maker's mark out of plastic. I highly recommend doing something like this for no other reason than it puts your name on it and more people will believe you when you say, "I made this myself..." Tandy does offer Makers Marks in their catalog but I haven't looked into that yet because my plastic one still seems to be imprinting clearly.

Bottom Keepers: On the briefcases that I researched , the ones that use the two belts that wrap around the briefcase all had the straps open on the bottom. I kept envisioning them as being perfect catches for the armrests on airplane seats when you are walking down the aisle. The last think I need is to be launched backward because I hooked an armrest..... to combat this feat, I added 4 strap keepers on the bottom of the briefcase to tuck everything in. It works well and also helps the briefcase stay rigid enough to stand up on it's own.

Buckle Keepers: A guy in my office has a briefcase with similar external buckles that are not often used. They have a tendency to flop forward and stick out. He is CONSTANTLY hitting elevators, door frames, and people with these loose buckles. I put a small hole in the leather behind the two buckles on mine, installed a brown eyelet, and ran loops of black paracord from the inside, out the front, and around the tongue of each buckle. I then added two slide locks stolen from my daughters winter coat (Shhhhhh......). You don't even notice it's there! This pulls the buckle up tight to the front and doesn't allow it to become a deadly weapon when you are walking behind people who are already seated.....

Oil is Good: You may notice that in some photos the leather looks a little lighter brown than in others. Over time and handling, the leather does lighten up. At the end of the project give all of the darker leather a nice heavy coat of Neatsfoot Oil. It will drink it up, so go ahead and do it again a few days later. I've recoat mine about every 2 or 3 months since I finished it and it looks new every time. If you're going for that "Indiana Jones" distressed look, then I'd only feed it Neatsfood once a year or so.

Step 12: Behold! the Project Is DONE!

Picture of Behold!  the Project Is DONE!

You should now be enjoying the product of your labor. As I mentioned, this is NOT a difficult project. Just a big one. Stitching everything by hand is a long, yet strangely satisfying process, but YOU can do it.

Final bits of free advice:

- Always take the safe route and buy more material, screws, hardware, and glue than you think you need. Trust me.

- Unless you are addicted to punishment, be prepared with a polite "NO!" statement when friends, family members and co-workers see it and say, "Hey, can you make one quick for me..."

-Get in the habit of adding extra time to your travels because people WILL stop you to admire and want to talk about your bag. YOU WILL BE LATE! Plan for this!!!

- Also, outside of home, don't ever let it out of your sight!!!

-Enjoy your bag, and start thinking about who you want to leave it to because it will last for SEVERAL lifetimes!

Cheers!

Nicely done....great work and an awesome looking bag. Love the details in your bag, from the umbrella holder to the inside pockets. Where did you find the pattern? Where did you get your stamp done?

ffrisell (author)2016-11-25

That is one great Instructable! I may have to try it someday if I can get my hands on some affordable leather.

offseidjr (author)2016-11-20

Fantastic 1st Instructable!

traste1 made it! (author)2016-10-21

Wow, very nice work and great instructable!

I was so impressed that i had a go at whipping one together myself and though i didn't do the internal pockets, some different materials, and minor design changes, but i think it's heritage is quite clear, and i am very pleased with the results.

I have never worked with leather before, so it was a bit of a challenge and a new experience.

A great "thank you" to you sir, very nice design!

Oliver200 (author)traste12016-10-21

Wow! If you just whipped that together you've got me beat! Mine felt like it took forever! You made a beautiful briefcase!!!

traste1 (author)Oliver2002016-10-30

Nah, i was just kidding. I ordered this one ready-made from Malaysia on ebay a couple of years ago, and it have been with me a lap or two around the globe, so even though i am extremely pleased with it it will never give me the pride and satisfaction yours must give you. Mine did loose a chicago screw or two, but i contacted the seller and he sent me a bag of them free of charge, so at $250 i am pretty pleased with it anyway.

When i first saw your, I thought "Wow, that looks almost exactly like mine", and it does unless you look at the details, really impressive work.

Did you use a pattern of some sort or its your own design?

JakeP2 (author)2016-10-26

Love your bag. It is really amazing and inspiring. I just bought a side of leather (attached a picture of what I got) and am going to start making one similar to your bag very soon. I also took your advice and j.b. welded the chuck from an old battery drill to a Harbor Freight arbor press.

I do have a question though, I cannot figure out how you made the pouches for the water bottle and umbrella... how did you do the bottom? I've tried to figure it out from the pictures, but just cannot see it. Any tips on those pouches would be very much appreciated.

Oliver200 (author)JakeP22016-10-26

Jake, sent you a PM. For some reason I can't attach photos on these replies.

caracoda (author)2016-10-26

Congratulations on the contest win! Your fingers might be sore from so much hand stitching, it deserves respect. Well done!

Oliver200 (author)caracoda2016-10-26

Congratulations to your win too! You do nice work as well, and it looks like sore fingers will be a thing of the past for you! Way to go!!!

CrazyLegz (author)2016-10-17

Very impressive build. What thickness of thread did you use?

Oliver200 (author)CrazyLegz2016-10-18

It was the 1mm Ritza 25 Tiger Thread.

CrazyLegz (author)Oliver2002016-10-21

Thank you! Hope your bag is holding up

Oliver200 (author)CrazyLegz2016-10-21

It's holding up great! God help me I'm making plans to start another one for my wife in black leather with a light gray leather interior.... hoping like crazy to win the sewing matchine in the Tandy Leather Contest!!! Lol

Mrballeng (author)2016-10-10

I'm speechless. First thing I did was think "Alright, where is this guy's leather working website. I buying something". Open up shop!

Oliver200 (author)Mrballeng2016-10-20

Lol..... I'm an engineer by trade. I'd never be able to finish because I'd always be adding "one more thing.."

dannylions (author)Mrballeng2016-10-20

WHOLEHEARTEDLY AGREE - WOULD PURCHASE THIS IN AN INSTANT - THE CRAFTSMANSHIP IS OUTSTANDING!!!!!

ArleyB1 (author)2016-10-20

That is so bad you should send it to me and I'll take care of it ;0) so you don't have to look at it .

Oliver200 (author)ArleyB12016-10-20

Lol...... NEVER!!!

JeremyS16 (author)2016-10-20

Can I just say to you, well done maker! I had one of those crazy expensive bags that I saved up for over two years and ended up buying used on eBay. It was awesome and amazing and worth the money, but even though I loved it as much as I did, it wasn't as functional as I needed it to be. For instance, I had a heck of a time figuring out how to carry my water bottle! So you solved that with your design, congrats again. I ended up selling mine due to the weight and the lack of functionality, but when I decide to own another one which I know I will, I will certainly (more than likely) make it myself!

pegbird (author)2016-10-20

Nicely done!

mike.strain.71 (author)2016-10-20

That is an absolutely gorgeous bag. I am looking into getting into leather work and your hard work is an inspiration. Thanks for the hard work and beautiful product. Well done.

Oliver200 (author)mike.strain.712016-10-20

Thank you mike! You can do it too!

jwmarsh1962 (author)2016-10-20

What was the most expensive part? Tools? Leather?

Oliver200 (author)jwmarsh19622016-10-20

The side of Kodiak leather was the biggest single expense.

TeresaM7 (author)2016-10-20

I have a bunch of leather upstairs that I got at a discount from Tandy a couple of years ago. I REALLY need to make one of these! Thank you for the wonderful Instructable!

HandyHomestead (author)2016-10-20

Wow, that looks almost exactly like a saddlebackleather classic briefcase, which are amazing bags at almost double the price (with a 100 year warranty) but you've got that "i made it myself" label which is way cooler. Very nice.

Oliver200 (author)HandyHomestead2016-10-20

Thank you! It seems like Saddleback took the old pony express leather messenger bag and added a carry handle and two straps. I really like the rugged look, and also drew some inspiration from Saddleback, Colonel Littleton, Kendall & Hyde, etc. I took all of the options I liked and rolled them into one bag. Thank you for the compliment!

JulieR99 (author)2016-10-17

Beautiful! So impressive!

_diyMATT (author)2016-10-17

HOOO leee SMOKES!

SherriH20 (author)2016-10-16

This is one in a million, Tim! I have seen it in person and it is indeed exceptional craftsmanship!

Danibrown29 (author)2016-10-15

That is official! Beautiful craftmanship. You have my vote. Congrats!

Oliver200 (author)Danibrown292016-10-15

Thank you Dani! I didn't know I had it in me! Happy to show it to you!

DustandDoghair (author)2016-10-11

Wow...what an incredible job! My DH had one of similar styling that he's carried for at least two decades...yours is even nicer! Beautiful color.

What an extra source of pride (in addition to the job, family and sacrifice) to carry on your way to work. SUPERB!!

DanielJ43 (author)2016-10-10

It`s beautiful, i like it.

Honestly I`m impressed, I know that stitching all those pockets, edges requires a lot of work. Awesome job!

Oliver200 (author)DanielJ432016-10-10

Thank you Daniel. It seemed like forever!! I put an accent stitch about 1/2" in all the way around on the big panels and pocket closures During the project I was kicking myself for starting that accent, with ALL of those stitches, that didn't really hold anything..... but now that it's done, it's one of the first things I notice when I look at it. Well worth the extra effort. Thank you so much for the compliment!

CraftAndu (author)2016-10-10

Damn! This is one really awesome briefcase!

Oliver200 (author)CraftAndu2016-10-10

Thank you! I hadn't done anything remotely like this before. I'm so blessed that I didn't quit and that it turned out so well! Thanks again!

StevenR133 (author)2016-10-10

just wondering if there are any patterns available for this? awesome project though!!

Oliver200 (author)StevenR1332016-10-10

Thanks Steven. Unfortunately there are no patterns. When I wanted to build, I looked all over but couldn't find anything. It was frustrating. Then I realized that every one is different, and you decide/modify as you go. I looked at other briefcases out there, figured out what overall dimensions I wanted, and just started cutting the leather. It's not as bad as it sounds! I know that's probably not the answer you wanted to hear, but that's how I did mine.

caracoda (author)2016-10-10

This is a great briefcase! Thank you for sharing and you do have my vote!

offseid (author)2016-10-09

What a beautiful bag! And such a great cover photo too. Got my vote!
