We get a lot of discarded Corona bottles. I live across from a park. We have a group of youngsters who meet up and drop their bottle tops on the ground. My friend used to pick them up because the serrated edges would hurt dog's feet. I thought it's a shame to throw them away so I'm going to do some bottle top art. Not sure whether I can pull it off but I like the idea of making art from litter. YouTube here I come!
