A Squedge is a squared wedge. Wedges make circles, but Squedges make squares.
The 22.5 Squedge makes a 16 finished square (16 1/2 unfinished) with 16 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. Its stash friendly! Can also make a 22.5 degree circle.
