I once saw a large quilt made with only this block. It’s a variation on the Mariner’s Compass. Very striking when finished in contrasting colors. I wish I had started making lots more of this block this past year, instead of just this one. Love what 1/2 sq. triangles can make..
All 1/2 squares started off as 2.5 inch squares. Sewn once diagonally And excess trimmed off. The larger Corner and middle setting squares are 4.25. I always lay my larger blocks out in the order it should go together before sewing all rows together. I’ ve caught a lot of mistakes early on by doing it this way.
