Sheet murals! Half of the fun is using non-traditional implements to paint with: hands, a feather duster, sponges, fly swatters, grass. The four cousins happily set about splatting paint on the white sheets (from a thrift store) that we clothespinned onto the chain link fence. We used tempera paint mixed 50/50 with liquid fabric softener (I’ve only found it at Walmart.) Clean up, of course, is just as fun, at least until the bucket tipped over with the child standing in it!
