1. Cut crafting foam into squares. The sizes I found most useful measured 9-inches by 9-inches.
2. Place the ruler diagonally across the square and draw a line with a pencil. Repeat in the opposite corners.
3. Draw a line 2 inches from the edge on all four sides.
4. Cut out one small triangle on each corner. 
5. Fold each remaining triangle over the corners to create the sides of the box.
6. Punch holes in the foam and twist pipe cleaners through the holes to secure the corners.


These are great to hold those small toys, pencils, art supplies and hair barrettes. And, they are perfect for organizing mom’s craft room, too!
