I managed to find the time to make this today. It's called a big buckle card. There is a tutorial on Stamping Up to follow. I used my newest Sarah Cards monthly kit for most of it and I remembered the name of the papers. See bottom of this post.
I coloured the sitting Tilda in with prismas and zest it. The little window at the top left hand corner was done with the word window punch and I stamped the welcome with a SU stamp.
Tilda was attached onto the actual belt strap so she could move when the card was opened.
Here's another view of the card, open. As you can see you adhere a "belt strap" and the card closes by putting the strip through the opening. The opening was made with the SU word window punch.
The card was finnished off with some blooms and ribbons which came with the monthly kit.
