I was intimidated at first to even try the die since I'm not that good with spacial activities. But I followed the directions that came with the die and put it together correctly the first time! I was elated!!!
What I've learned - the cake is only round when you put it together. Once you fold the card, it's forever an oval shape. It's still a WOW though, and one anybody would love to receive.
More details: It's a Regal Rose card with the sentiment from On Your Birthday stamped in Chocolate Chip ink. I used a 6" x 12" piece of Chocolate Chip card stock on the die, then cut strips of the polka-dotted paper from the Sweet Always pack (still Buy 3 Get One Free thru May 31).
