Skirts come in tabs with the ends uncut. So the first thing to do is slide a skirt band over the pointy end and roll it past where the tool separates. Then hook a couple of skirt tabs by the end where all the cut pieces are joined and pull them into the barrel of that tool and partially out the other end. Now you roll that band you preloaded onto the skirt. Pull the skirt out, cut the ends off and you have a skirt.
