These cards have been floating all around splitcoast stampers and I finally have made a couple of them. I put this one together for one of my daughters friends!
Here are the directions: You take a 12x12 cardstock and cut at 6 inches. They you place it horizontally and score at 2, 4, 8, and 10 inches. Then you turn it vertically and place paper 1 1/2 inches in and cut from the first score line to the last score line. note: you can prescore this first if you would like! Then you just fold up the card. It will fit in a normal size envelope! If you would like more details let me know!
