Really straightforward - just paint your design onto the plate, cut a circle out, and tape your picture to the back. We had these Simpsonised photos of ourselves kicking around so decided to do a set of three to hang in a row (fixed together with taped pipe cleaners). Matthew really enjoyed making them and is delighted with the result (so am I!).
Here are some more ideas:
- create a pattern with sticky mosaic tiles or beads
- make a collage with tissue paper, petals or lengths of pipe cleaner radiating out
- (for older children) write out a poem or passage from a book in a spiral round the edge
