I was inspired by this post by Debra I used a different set than she did but the rest is the same.

To make this bag I cut a piece of gift wrap into a 12 X 12 piece, I scored at 2 inches on one of the ends (this is then the bottom) and at 1/2 inch on one of the sides of the bag. I folded the paper up to the 1/2 inch score line and then folded it again to meet the same line. I used adhesive on the 1/2 inch score line and attached it to the opposite side of the bag. Then I folded the bottom in like I was wrapping a present. I hope this makes sense.
