One day I came home to a window shelf full of these cool monster that dad had made with the kids. Especially our 5yo son loved making these. Usually he likes crafts but our daughter is the one loving it, maybe the key is to have fathers come up with the ideas to get sons excited too?!
First they applied a layer of acrylic paint, which my husband dried in the oven. Then kids drew how they wanted him to cut the mouth and after that they made the eyes etc.
