Line up the cutter with the circular impression made in Step 1. Push down until the pivot screw punches through the backing (you'll hear a pop). Rotate the cutter two or three turns with firm, even pressure. (Avoid making too many turns or you may slice through the padding that supports the patch.) Remove the damaged piece, then use the same method to cut out the replacement patch. Draw an arrow on the back of the patch pointing in the direction you rubbed the fibers to make them stand up.
