This is a window card. I hid the outer layer of the cut in my Gypsy. The second sheet is attached with a thin line of adhesive. It is patterned on one side and white on the other and makes it perfect for writing inside the card. Here is a picture of what I'm talking about. Diane at Capadia Designs does a great job with this. She has an awesome step by step photo tutorial on how to do this. You should definitely check it out.
