I put an insert on the bottom so that she can stand it up on her desk. What a hoot.

I utilized a little strip of DP that was leftover, on the inside. I normally leave the inside of my cards blank because I never know who or what I am going to use the card for. Since I made this specifically for my DH, I went ahead and completed the inside. I love the key, and I love that I had fibers to match the colors of the DP.
I just may make a bookmark using the remaining DP and fibers. What do you think? Something that says Books are Your Key to Adventure?
