It so happens that once in a while my bike hits something sharp and gives up, and as I am a woman of handyness, I change the tube myself. I have this need for taking everything into consideration when being creative (and I hate to throw things out that just might just become useful for something I am not yet aware of) so this happended. The necklace is 5-8 pieces in different sizes, messed around and tied together with other thinner (and very elastic) pieces. The straps can also be mixed with leather pieces to create an even more cool look, and as a bracelet. I did that, but a woman was so into it, i let her puchase it before getting a shot at it. Estimated time to make: 30 minutes.
