This one is pretty simple. Just make sure that you leave a little extra room on the edge when you cut your paper, fold it over, lining up the sides and/or the pattern to help fold on a straight line.
It's often possible to get the patterns to line up if you play with the width of the fold-over. You might even want to feature the fold instead of hiding it at the bottom of gift!
