I have done several of their kits and really liked doing them. You use a tool that is much like a crochet hook that is flattened on one end. The foamboard is covered with thin foam sheeting, so you don't have to use batting. The picture is cut into the foam and the styrofoam board underneath. You get a paper pattern for cutting out pieces. The pieces need to be larger than the area they cover so that you can push the edges down into the slits.
