If you’re a cyclist that lives in an area with poorly-maintained infrastructure, you’ll likely have plenty of punctured inner tubes begging for reuse. Consider crafting them into a rugged, hard-wearing pencil case with this design from [Yorkshire Lass].
[Yorkshire Lass] does a great job of not only explaining the basic design of the pencil case, but also the unique techniques required to work with inner tubes in this manner. For best results, the tube must first be straightened by stretching it for some time along a flat board. Strips of the rubber must then be cut to suit, and then assembled into the pattern to make the pencil case. Sewing up the case also requires some special techniques outside those used in regular sewing. That’s largely down to the fact that rubber can’t be pinned in place without leaving a permanent hole in the material. Thankfully, the write-up explains all the traps for those new to sewing inner tubes, which we’d have to suspect is most of us.
Assembled properly, you’ll end up with a pencil case made of far tougher material than most. Plus, it makes a great fashion accessory to flaunt to other bicycle or recycling evangelists at your school, college, or workplace. Even better, there’s scope to run a group craft session with your local bike group given everyone surely has a few dud mountain bike tubes laying around.
