Using pre-cut foam shapes for a fun Valentine's craft makes it fast and easy and lets you and your child focus on the messy not the prep! 1. Gather your materials. You will need a rolling pin,a paper grocery bag, some self adhesive foam hearts ( we found ours at a local big box store), red paint and some foil or newspaper to roll the paint in. 2. Stick your foam hearts on your rolling pin. 3. Roll in the paint. 4. Print! This can be used for wrapping paper for your special Valentine!
