These monsters were totally inspired by SouleMama's book The Creative Family. I'm not sure that she did stuffed paper, hers were probably fabric.
We used a couple of drawings and sewed them onto a backing pieces of paper using the sewing machine. Make sure you leave a gap for the stuffing if you try it. Then you can cut around the edges and stuff it.
We used shredded paper for the stuffing but cotton wool would work well too. #1 gave them to his kindy friend as a get well gift. I think they'd be lovely made from cotton and embroidered or drawn with fabric pen. I might try that somtime, surely embroidery can't be that hard can it? Well I guess I won't know till I try anyway.
Note - apparently sewing paper is very bad for your needles and makes them blunt, oops.
