Takeout boxes (foam plates would also work)
Fabric paint (I used Fabric Creations Soft Fabric Ink and it's the best!)
Step 1: Cut out flat foam squares from your takeout box(es). I just ran into a restaurant and asked for a bunch of boxes and they gave them to me for free, but I also saw them at Walmart by the paper goods. Or if you eat out, save your boxes!
Step 2: Draw or trace your design on the foam.
Step 3: Cut the outside edges of your design.
Step 4: Apply paint to the foam.
Step 5: Press stamp on shirt, and remove.
Step 6: Let dry. Follow any additional instructions for your fabric paint.
Isn't this the cutest? And think of the possibilities! They are never-ending!
