Rubber inner tubes are a wonderful material to use for a koozie because of their insulation properties, durability, no slip grip and up cycle potential.
Since these are hand made it also makes it easier to remember which drink is yours ;-)
For this project one inner tube is more than enough for a koozie.
Two standard bicycle inner tubes can usually cover a six pack.
Up-cycling is the process of converting waste materials or useless products into new materials or products of better quality or for better environmental value.

Step 1: Cut the Inner Tube
Cut the inner tube horizontally so that it is one long piece.
* The best place to cut it in order to save materials is by the metal air valve.
Next cut the inner tube again vertically, as shown below.
* Most inner tubes have lines that can serve as guides for cutting straight lines.
Step 2: Measure Inner Tube Width and Cut Sections
Once you have a long flat strip cut it into two sections that fit around your glass.
Step 3: Sew the Inner Tube Pieces Together
Slightly overlap the strips so that you can sew them together.
I used the industrial strength walking foot at the techshop that is awesome for thicker materials.
Theoretically a standard sewing machine will also work.
Step 4: Sew the Sleeve Closed
Sew the sleeve closed as shown then cut off any excess.
Step 5: Turn the Sleeve Inside
The last step is to turn the sleeve inside out, fit it over your drink then sit back, relax and enjoy a beverage.
I made it at the TechShop!
