Cut out and save the front pockets. There are two ways to do this. You can flip the jeans inside out and lay the pocket flat, Cut the fabric in a rectangle, about an inch from the end of the pocket. Cut through the side hip seam, the cut following the seam to the waist. This leaves a flat square pocket that can be sewn onto anything. These large pockets make a great addition to a crafting apron.
You can also remove the decorative fifth pocket, on jeans that have them, but in so doing you sacrifice the larger pocket.
