82 Plastic containers and caps from laundry detergents- I reuse the caps from my laundry detergent bottles for mixing paints or water dishes. I have also used them on strings of light (decorated with scraps of fabric or paper.) Containers from cottage cheese or yogurts work well to keep paint in when I'm working on a project and have to walk away from it. I just lay a damp paper towel over the top, pop the lid on and the paint stays wet. (Just don't forget about it and find it months later like I did....YUCK!
These are all great ideas people! Keep 'em comin' =)
