I absolutely love it when I can use my scraps to make something useful! I had friends over one night and they left behind scraps on my table. I told them I would take care of it, actually thinking I would just put them in my scrap bin. I sat down the next day and made what I call "inside out" cards. It is where I actually lightly embellish the inside of a card to match the outside. Here are a couple of pictures to show you what I mean.
Excuse my fingers - I had to hold the bottom of the cards because they kept wanting to flip up. I am just showing you two, but you get the idea. I think it adds more to the card to decorate the inside, as well as the outside.
