The Valentine card that Dina created is a perfect example of how you can use a metal die with Art Squares. In this sample card she used 4 - 1.5" white Art Squares and one at a time ran 3 of them through the die cut machine with the hearts die. Because the Art Squares are matboad thickness the die will not cut through the material, but instead leaves an actual incision into the square. It's a neat trick to add a textural element that can be further enhanced by coloring!
