1. Lay your sweater flat on a hard surface, lining up all edges. 2. Cut a straight line about 5-7 inches above the waistline. 3. Then, fold the sweater on top of itself, with the arms overlapping. 4. Cut another straight line, about 10 inches from the wrist of the sleeve. *Note: after cutting the leg warmers, you can add the lace from today's Lace Socks DIY.
