Studio Light Butterfly Card Dies, part of the Grunge Collection, is a wafer-thin die set that includes 7 pieces and creates an interesting square card shape design with a butterfly on the folded edge. The finished card size is approximately 5.5 x 5.5 inches. You can layer the wonky-edged squares to make a more formal note card. This die set is perfect for adding a unique touch to your card-making projects.
