I first made these covers for the mini legal pads at least 6-7 years ago. Sort of an old idea that I decided to revamp as a small convention gift for some special friends.
The cover has an inside pocket and all it takes is 1 sheet of 8 1/2 x 11 card stock. You can make it in minutes! Don't have a template right now. I did it by tracing an old one I had. I bet you can find it on a stamping forum.
