Actually it is a pattern for a corner book mark. Easy and quick to create.
It is currently for sale at MooTwo - but you can find a coupon to get it for free this month only in this forum. (must be registered in store) Come join me for the challenge!
Yep, another contest. This one with secret identities, so I can't tell you which one, but there are lots of great kits with this color and theme over at The Studio.
