Who knew you could glue bits of bicycle inner tube to a rolling pin to make a clever rolling stamp? Aparently ynze on Instructables did, and shows you how, too.
Using a rolling pin, a used inner tube and some sticky tape, you can make a really cool roller stamp. By really cool I mean really big. You can make prints as wide as the largest roller pin you can find (43 cm wide is standard), and as tall as you wish.
