Teachers! Did you use this instructable in your classroom?
Add a Teacher Note to share how you incorporated it into your lesson.

Step 1:

First of all grab the materials. Here I'm using a glass bottle from a... juice... a wheat juice... fermented and distilled wheat juice. If you too young to drink whet juice, ask your parents to buy you a bottle or two. Basically you need a flat bottle with a simple regular shape like one on the photo. Also I decided to incorporate the label, I had on the jeans into my design so it's also here.

Step 2:

For making a flask like this, you don't need any complex patterns. All you need is rectangular piece of matter with lenght that allows you to wrap it around the bottle and have a bit of leftover. For the height, measure (along the flat side of the bottle) from the centre of the bottom to the part of the neck, where the cap is begin, and add a couple of centimeters to it.

Step 3:

Now wrap the piece you have around the bottle and pull the edges together tightly. Use some sort of a marking device to make a mark where the flaps meet at the surface of the bottle. This will give you the exact width of your rectangular.

Step 4:

Add aproximately 1cm to each side of your previous mesurement.

Step 5:

Cut off the excess. Here you can see that I've already folded top and bottom edges to the back of the piece, but you really need to fold only the top edge (I realized later, it was an unneccessary step). I used a glue stick and a binders to temporalily fix it on place.

Step 6:

Now wrap the piece arond the bottle. Aline the top edge with botton of the cap and a middle with the middle of the bottles "face". I included the original seam from the jeans, so it served me as a guide. Place the lable where you want it to be on your finished flask and mark the corners. I putted dots underneath the label near to the edges.

Step 7:

Lay everything flat and secure the label into place with a glue stick to prevent it from mowing during the sewing.

Step 8:

Take a look at your neighbor's house and sew the label down.

Step 9:

Now fold your piece as shown on the photo and use pins to secure the long edges.

Step 10:

Sew the edge along the marking line, we've made earlier.

Step 11:

When the sewing is done, you'll got a sleave tube. Try to pull it onto the bottle to make sure you've got a snug fit.

Step 12:

Glue the excess material down.

Step 13:

Fold your sleave flat, making sure you have your seam right in the middle. Secure bottom edge with pins.

Step 14:

Sew the bottom. Earlier I've said that you don't need to fold the bootom edge. Just sew it leaving a 1cm of an excess.

Step 15:

Now you have a bag. Turn it inside out and push/pull the corners out (I used a chopstick as a help). It'll help to keep everything aligned when we will be puting the sleave ono bottle.

Step 16:

Now we are ready to put our bag-sleave onto the bottle, but first stick a couple of pieces of a doblesided tape to the bottle neck (on the sides where the "shoulders" are). It is not necesserally but it will help you to get more accurete final result more easily.

Step 17:

Pull the sleve onto the bottle.

Step 18:

Push the corners at the bottom inside the sleve layng them flat. I used an awl. Make sure the sleave is pulled tightly up the bottle.

Step 19:

Align the material around the bottle neck and stick the sides of the sleve to it (remember the tape?..).

Step 20:

Make folds around the neck as shown on photo, making sure you're keeping everything even and tight. Now sew the edges ignoring confusing unremovable markings I've made. I didn't documented the stitching process but it simple enough. I used two neadles on one thread. At first I've made a couple of loops arond the edge at the top, then a couple (do as many as you need) stiches along the edge using a saddle stitch, and then a few loops around the edge to finish the seam. Neadlenose pliers helped me while sewing.

Step 21:

Now your flask is ready. You may also want to decorate the cap to match your design by painting it, or by removing existing paint with a dremel tool and a wire brush leaving just a bare metall. My was ok to me so I didn't bothered.

On the photos you can see a few flasks I've made this way. Definitly you can adapt this methot to your own creative needs and desires, and I hope I was able to provide you with the inspiration to do so. Also, be carefull with the wheat juice. Thank you for your attention and have a nice something.

    What about sewing the top to an exact fit, then using the zipper from the fly to put in the bottom so the bottle can be removed/washed/replaced?

    Well, it's an option, but initially I was driven by the idea of using simple rectangular shaped piece of material to wrap it around kind of complex shape like a bottle with need to have only two dimentions instead of making patterns that fit only this particular bottle. So I tryed not to alter the rectangular shape in any way, but, yeah, it's not a dogma.

    This is great! I actually will use this idea for my giant bottle. The only difference will be that (because it is so big; 2 quarts), I am going to make "suspenders" for it so I can take it off when I clean out my bottle. I voted for this. Love using old jeans for projects! Thanks for sharing!
