Instructions . Pick out a pair of shorts, any fabric, that you would like to work with. . Zip up and button the shorts so that the seams line up evenly. . On the side of each leg of the shorts, mark where you would like to start cutting. Make the mark long enough so that it is viewable on the opposite side of the jeans. . Find a piece of cardboard, and a small circular shape. Trace two straight parallel lines, about 2 inches apart, on your piece of cardboard. . Take your small circular shape and in between the lines, trace half of the circle about 4 or 5 times. . Cut out the circular shapes that are on your cardboard, and one leg at a time, hold it up to your fabric and cut along your cardboard cutout. . Repeat on the opposite leg.
