In Holland, there are approximately 16 million people and 13 million bikes. Multiply the number of bikes x 2 and you get a rough calculation of at least 26 million inner tubes.
What happens to all those inner tubes when they are beyond repair? Jewelry designer Sasja Saptenno has found a creative way for people to accessorize with them! Sasja obtains her materials from bike shops, neighbors, and even off of her own bike!
Have a look at Sasja's website, (accessorylab) for more wonderful creations, and you can read more on her blog.
