I know that the re-enactment people might hate me, but making celtic leather shoes is so much easier if you have a laser cutter (as we do in our hackerspace "Mainframe"  in Oldenburg (sorry, web page is in German only right now)).

I did it for a baby (6 month), but you can easy scale up and down the template. And if you do not have a laser cutter, you can do it by hand, too. I will mention how in the steps.

Step 1: Prepare the Pattern

Since I already had celtic shoes with I wanted to use as a pattern, I opened the laces and laid a shoe flat on the table. Then I took a picture. I imported the picture into a graphics tool (I used CorelDraw, but OpenSource Inkscape should also work).
First I tried to vectorize it automatically, but the result didn't look good.

Then I put the picture in the background and draw the outline with the mouse; I only placed a point at each corner, and then smoothed the lines (there is a option for line objects; sorry that I cannot give the correct technical terms, since I'm using the German version of the software). The second picture shows a screenshot of the pattern drawing with the line option symbols.

In addition to the outline, I also drawed a little circle for a punch hole. And then I cloned it multiple times and placed it at each hole location of the photographed shoe.

Be sure to clone the circle and not to copy it. If you copy and change the dimensions of one circle, all other circles remain the same. If you clone, you can change all circles at once. I wanted to have a template that scales!

The final pattern (as DXF file and as PDF file) is attached.

To scale it, I looked up the length of the foot (for a 6 month old baby between 8-11 cm), and drawed two ellipses into the template to represent the foot. Then I scaled the whole thing until the ellipses had the right size.

Step 2: Prepare the Laser Cutter

If you do not have a laser cutter, skip this step.

To cut something with a laser cutter, you first have two important things:

1. is it save to cut it? The laser beam will burn the material where it cuts. You do not want to have poisonous smoke or explosions.

2. which settings?  The most important settings are speed (how fast does the laser beam move) and intensity (how strong is it). If you use not enough power, you might not cut the material. If you are to slow, you might get big burns at the corners.

For 1., we were pretty sure that it should work, since leather is a natural material, and many people use soldering iron to make designs in leather. Nevertheless, since most leather was somehow colored, we had to be sure that the color does not contain chlorine, which when burnt by the laser, creates a gas that destroys the laser’s mechanism. So, we took a small sample of each leather and burned it with a lighter. There was no green light in the little flame, so we think that there was no chlorine in the leather.

For 2., we tried out cutting a sample with different settings and noted them down. The picture is not meant to be readable -- each laser cutter has its own settings, and if you do not have one by yourself, ask the owner how to do this step!

Leather can be cut pretty easily. On our 80W CO2 Laser we use the following speed settings with 70% power:

1.4mm thick leather: 100mm/s
1.7mm: 70mm/s
2.1mm: 50mm/s
4.2mm: 25mm/s

Step 3: Cut the Leather

To be honest, we did not cut the leather immediately - we tried it with Polypropylen first (a plastic which is good to laser). So I produced two little plastic shoes. Later, we tried to cut leather, but we forgot to re-focus the laser cutter, so instead it produced brand design in the leather (right side of the picture).

But then we lasered with the correct settings and produced two little leather shoe forms including all the punch holes. This saves a lot of time in the last step!

Leather is a nice material to cut. However, it really smells burned (well, it is burned). So make sure that your exhaust system works properly.

The leather will smell, too. I used a cream colored leather and the cutting edges all were pitch black. But then I washed the leather and let it dry; the edges changed to a light brown, and after 3-4 days, the burned smell went away, too.

If you do not have a laser cutter, you need sharp scissors and a hole punch. You can print out the pattern and transfer it with a hard pencil on the leather.

Step 4: Final Step: Sew the Shoes

To sew the shoes, you only need a thick needle and the draw string you want to use. I used a silk band, but you can use other materials, too.

Sewing the front is easy (just a look, make sure that you enter each of the lobs from the same side).

Sewing the back is a little bit more tricky. In the following scheme, "R1-A" means "enter hole R1 from the outside", and R2-I means "enter hole R2 from the inside" (outside means "aussen" in German, thus the 'A'):

R1-A R2-I N1-I M2-A L3-A L4-I M3-I R5-A R6-I L6-A L5-I N3-A R4-A R3-I N2-I M1-A L2-A L1-I

With this scheme, you get a nice cross stich on the back of the shoe. The two ends of the string can be drawn inside, to make a knot there, which will be partly hidden by the two sides (L1-L6/R1-R6).

Step 5: Done!

That's it!

To close the shoes, you could either attach a button on one side and make a backstrap on the other; or you just do two strings with can be tied together. And here you see little Ronja wearing a shoe for the first time in her life!
<p>This is a great pattern. I made a pair from another pattern that was for iron-age shoes that were similar, but no where near as nice. With your pattern I made a jean material Celtic shoes that I really am pleased with. Thank you for sharing.</p>

<p>I am making a test pair out of felt. How does the back lace up? Thanks. They are cute. I was thinking i was making them as slippers for my daughter, but my sizing was off and they are big enough for me :)</p>
<p>Felt should be nice, too! For the back: have you looked at Step 4? I tried to clarify that by that numbers to show in which order and direction you have to sew them. Let me know if you need further instructions, I'll be happy to give them.</p>
Hello, do you have another program to run this? I have tried every program I have, but to no avail. I've run a search on line and everything that comes up has a price tag. Thank you for this great instructible.
Ok, I got inkscape working. Now I just have to learn how to use it. LOL!
Yes, Inkscape is great and can do just about anything you would want a vector graphics program to do, but I find it lacks an intuitive design.
There should be a good community out there to help you with Inkscape. It's a good tool for designing patterns, in our fablab, we use it for the Lasercutter, the Styro cutter and as far as I know also for the milling cutter. <br> <br>I only used CorelDraw because I have a license on my work computer and I'm used to it.
any chance of the design file being posted? This is a really great 'ibble. I want to have go at making these.
It is! You find the download link in step 1 (in DXF format). Let me know when you need other format.
Excellent thanks, stank the house out with cutting leather on laser last night!
Great! Hope your friends don't hate you (and me) for this :) <br>Any results yet?
Not sure I understand this, however I am going to scale the design and make some larger ones. However I am waiting for a fume extractor for my laser before I cut any more leather! <br>On the trial ones I cut I noticed that some holes are very close to the edges so I might well modify these slightly before doing another cut.
When scaling the design, you have to consider two things: <br> 1. that the pattern fits to the foot (scale the outline) <br> 2. that the holes fit to the draw string (scale the little circles) <br> <br>The holes at toe side of the pattern are close to the edge, but they also do not have hold a lot of power - with the leather I used, it was not a problem. But of course you can move them more inside. <br> <br>And yes, fume extractor is a must-have for lasering leather. Have fun!
cool mocs! Great job. I like the pic for step five. It looks like Ronja took the picture because it's from her point of view! funny!
C'est fantastique!
Is it possible to get PDF format? Would it be accurate if I just printed it for a pattern?
Thanks for asking, I found out that I can not only attach images but also other files. I attached the PDF and the DXF now to Step 1.
This is a great 'ible. In a pinch, you could even use this method to cover old shoes where the soles had worn out.
Good idea! Or you could make covers that you could wear over shoes when you enter delicate areas (e.g., for a historic wooden floor).
These are absolutely awesome!!!
Awesome! Look very professional.
Cool
lovely
