Stacked lids, bottle tops and caps. Fun for kids, but would also make great garden art! I'd think the trick for doing this project is to collect as much different color, shape & size of lid/caps as possible before start putting them together.
Cardboard or wood cut-out decorated with caps from juice bottles, etc. This makes me want to make art with the kids that we can hang in the classroom and keep there! A lovely recycled wall art craft. Would make a great Earth Day cooperative project
