I wish I would’ve seen this soooner! What a great project for kids. Here’s a couple of tips for doing clean handprints. Use acrylic paints, they are washable. Instead of dipping the hands into the paint, which is really messy, use a foam paint brush to apply the paint to the hand then press immediately and firmly onto the paper. Wash off with soap and water or a baby wipe. Best tip: wear aprons or paint smocks to protect clothes. project idea via E is for Explore.
