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.
With this art project idea, you can learn how to make suncatchers the easy way. Glass Gem Suncatchers are totally effortless, but the end result is simply stunning. Even little ones can get in on the fun by choosing the colorful glass beads.
The Chic Technique: Plastic Cup Sun Catcher Mobile by Erin Barnes This is made out of recycled plastic cups. Shrunk like shrinky dink plastic and hung so beautifully into this mobile/sun catcher. What a great older kid project as well.
