I made these setting triangles and when I tried to sew them I realized they are not right angles...don't they need to be right angles?
Top picture is how to make the triangles. Cut 13 1/2" square. Cut that into 4ths to make triangles.
Lower pictures is how to sew them together. Shouldn't the point of the triangle that attaches to 2 squares be right angles? Mine are not. What am missing here?
