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.
This would be a very cool bed for kids who have to share their room with a brother or sister. Build 2 and the shutters give them space from each other. or just have as a little nook space, nice and cozy to read your fav books and chill out
