This year Reu helped me make Christmas cards and wrapping paper with these "sponge stamps". They are very simple to make, fun for the little ones to play with and are easily cleaned (so can be re-used many times). I used small offcuts of timber, a packet of new kitchen sponges and a hot-melt glue gun. Cut out desired shapes in the sponge and glue to the wood. Let dry. Mix up some washable, kid-friendly paint or inking pads and print away on sheets of craft paper or plain brown wrapping paper, cardboard, whatever else you like... wonderfully messy merry making!
