I used a sq in a sq method that used 2 square, one larger than the other. Sewed around all 4 sides and then drew from corner to corner of the larger block and trimmed it back to make the triangles. I know the points werent a good 1/4 in this way but was a lot quicker. If anyone has a source for the pattern I would love to have it. I can't find it anywhere.Thank you.
