Every year I make sure everyone knows about this lovely little Christmas craft idea early enough to get them done in time! They are so easy to do and very effective. I made my first ones 2 years ago when Thing 5 was just a few months old so some of ours are really small and cute. Ideal for baby, toddler and small children's hands. Ideal for the older children to paint themselves although I did get quite annoyed if they didn't do it quite right so I painted the ones we were giving as gifts.
You make up the salt dough and roll it out, not too thin. Press the child's hand into the salt dough and then carefully cut around the hand print shape. Don't forget to put a decent size hole in it for hanging once cooked and painted.
