The Dollar Tree store scores again.
Some ceramic heart bowls seen on Pinterest started my search for rounded plastic bowls to use as forms. The only problem was that bowls all had indents on the bottom, which would take away from the smooth look. I found the perfect solution with these colanders from the local dollar store. They are absolutely smooth and round, and even add a dot texture. Students may add a textured edge with a stick, or leave them smooth for a candy heart look.
