I got an order to create a card for a girl's 20th birthday. The first thing that came to mind was making something that had either 20 doors or 20 flowers or 20 something (you get the idea). This is what I came up with. I'm pleased with the way it turned out. It also took 2 1/2 days to make. So definitely not a money maker, but since I know the person it's going to, I figured I'd put my heart in there too.
It's a five page accordion card, with you guessed it - 20 doors. Lots of interactivity, besides the Peel Offs I put on acetate inside the doors, there are words under the doors and on top of the doors and a bunch of other stuff too.
