We did a thing for dh last year that was really fun, easy, and cheap.
Have the kids trace their hand on a canvas (or help them do so if they are too little) and write their name next to the hand. Then the parent uses a black permanent marker to go over the pencil tracing and name. Then give the kids water colors to color in their hand. You can spray with sealant when done to protect them or frame them.
i got two of these kits today... they look like so much fun. i have wanted the kids to do them for a while now. i didn't have a coupon, but they were on sale! YAY. i can't wait to see them in my garden.
