I got this Handprint Ornament Kit from Walgreen's during the after Christmas sales for super cheap. Having done the kits with my son where you mix the ingredients and having no luck, I was excited to find this ornament kit because it involves no mixing! It reminds me of the Crayola Magic modeling clay- it is super light with a marshmallow feel to it.
I also loved it because if you mess up the hand impression, all you have to do is roll it up into a ball, press it back down, and start all over again. I wrote the year in with a pen. After it dries, it does not completely harden like regular clay, but does get somewhat hard. I wish that I would have had this when my son was a baby! It is meant to be a Christmas ornament, but I plan to display it year round.
