Pinkie for Pink: Kids Christmas Art Projects - use the kids' feet print for the "mistletoe". Once dry paint on ribbon, lettering and polka dots. Maybe this will go better than our attempt to make handprint angels.
Watercolor tree art project, great for very young kids--adult places masking tape in pattern of a tree, kids paint over as much as they want. When you remove the masking tape, a tree is waiting underneath!
