Here's a quick and easy card you can make for Mother's Day. All you need to do is roll out a circle of paper clay ( sold at Michaels and Daiso). Push the child's hand in the clay. Let the hand print dry for a day. When dry, glue it to your choice of card stock. This would also look cute framed in a shadow box.
*Paper clay is very light so it won't way down the card at all. You can also paint paper clay.
