Wedges make circles, but Squedges make squares. The 18 degree Squedge makes a 16" finished square (16 1/2" unfinished) with 20 Squedge pieces. Use the precise slots for marking the inner shorter pieces. Open the packaging and you have another Bonus pattern, a terrific table runner, 22" x 72". Yardage amounts for backing and binding are listed here: backing 1 1/4 yd, binding is 1/2 yd.
