It is even possible to crochet bicycle tubes, Michaela shows us how.
Michaela says: “I crocheted this door mat out of old, broken bicycle tubes. After several attempts I found out that it’s the easiest way to use a tent peg. I cut out the valves and then slit the tubes lengthwise. Washing the tubes has to be done thoroughly because the valves are covered in a thick layer of powdered talc from the inside. Then you have to cut the tubes in stripes and either tack (like I did it) or sew them together. The result is a long “thread” which you just crochet and then you’re done.”
