Using the 21-gauge square wire, straighten, measure and then cut 3 or 4 pieces, each 5-1/2 inches long. Place these wires side-by-side and tape the bundle near each end. Measure and mark the center at 2-3/4 inches. According to the size chart that follows, measure and mark the required distance on each side of the center mark.
~ For ring sizes 5 through 8 = 5/8 inch
~ For ring sizes 8 1/2 through 10 = 11/16 inch
Straighten, measure, and then cut one piece of 20-gauge half round wire 6 inches long. Use this wire to make two sets of wraps, wrapping from each "side-of-center" mark toward its respective end, 4 times to show. Reserve the remaining wire for later.
Pro Tip: Note: "4 times to show" is wire jewelry shorthand; it means that there are 4 wraps showing on the front of the piece, with the cut wire ends on the back.
