I have been wanting to try one and had no idea what it even was. Then I found this one on this blog and she gave a very good tutorial so I tried it and its super easy. Try it!! I made one with a ribbon to close it and one without a ribbon. I wanted to see if the one without the ribbon would stay closed and it did not so that's why you see my hand holding it closed in that one :). I laid a telephone book on the card that did not have the ribbon and by morning, it was closed pretty good :). So you don't even need the ribbon if you want to leave out that step. Now i wanna make more :).
