LOVING this Snowman Handprint Ornament. We have a big bucket of Crayola Modeling Clay that would work PERFECT for this. Basically all the boys need to do is roll out a ball into a circle and push their hand imprint in. Wait a few days for it to dry, then decorate with Sharpies (which we have a TON of in all colors)! TOTALLY cute idea, and definitely something I would hang on the tree.
