Ball pit balls are one of my favorite throw away items to create with. They can't be recycled where I live (or in most places), so I enjoy trying to figure out what their new purpose should be after they've outlived their usefulness in the pit. The pink in these earrings comes from leftover parts of reworked and reimagined ball pit balls.
