Here's another great Valentine's Day craft idea from Maro Oikonomou from Greece. It's a finger painting craft to make a heart tree. The palm and forearm are the tree and use thumb prints hearts for the leaves.
brown and red paint and brushes
Brush child's hand and forearm with brown paint and press onto white paper to make the tree. Wash their hands.
Put red paint in shallow dishes and show the kids how to use two thumbprints to make a heart. Put hearts all over your tree. Happy Valentine's Day.
