Here's a shoe house file I found in the Pazzles Craftroom. I made it into a small gift tag, but it can be used for anything your mind comes up with. This particular gift tag won't have a string tied to it. I'll be gluing the back onto the top of the box or front of the gift bag.
The original file is a paper piecing. I added the back by duplicating the front and adding a score mark where I wanted it to fold.
