HST question
I have a pieced border with a pinwheel. The size of the pinwheel block (before sewing to adjacent blocks) is 2 1/2". The pattern says to cut 1 7/8 squares, and then cut the squares into triangles and sew the triangles together to make the pinwheel. I was wondering why they didn't say to make the half square triangle units using the two-square, diagonal line method. Wouldn't the result be the same? It seems to me the two-square method would be quicker and also avoid working with bias edges. Am I missing something?
