I'm a big fan of Karen Burniston's pop-up dies. I saw a very pretty and very clever card on her blog the other day, and I knew I was going to have to try it. It featured her Tag Book Pop-Up die. I've made a few cards using this die before, but this one used acetate for the inside pieces. It gave the illusion of the cherry blossoms she used as floating. I didn't have the cherry blossoms, but I did have an Impression Obsession branch and Heartfelt Creations dogwoods -- so that's what I used on my card. The front was pretty easy . . .
. . . the inside took a bit of concentration.
As you can see, I glued the die-cut pieces directly onto the acetate "frame" and they appear to be floating. Here's a photo which shows the "floating" elements a little better.
This was a very fun card to make.
