One Christmas make that can be done with children of all ages is paper snowflakes. I have put photo's at the side so you can see how easy it can be done. Start with a circle and fold in half, half again and again. Then simple cuts into the sides.
May's Monsters Pretend Monsters are always fun for children to make. May is left handed so most makes we do include cutting out, she managed really well with the monsters below. The best scissor practice, I find is always the ones, the child doesnt realise thats what they are doing.!
