It's a simple gatefold card but this one has a window. :) To make this, score the 8-1/2" X 5 1/2" cardstock at 2-1/8" and 6-3/8". This gives you the "gate". Then, open the gate and place any shape die that you like and put it inside the card with the blade face up and close the "gate". Run it through your die-cutting machine and when you open it, you'll have a wonderful window in your card.
If you don't want your "gate" to flop open, you can tie some orange/onyx baker's cording around the top and bottom of the card.
Have a wonderfully creative day!!
