Then just cut on your line, press them open and trim to 3 1/2" square.
I just read in a book called "Stash and Splash" that if you cut the square 4 inches and use a regular presser foot to sew on both sides of the diagonal line, you will have a 31/2 square without having to cut down to size. On almost all sewing machines the presser foot measures 3/8 inch from needle to edge of the foot so you are making a larger seam to compensate for the larger square. How about that! Rita
Cool. You may not have to cut down to size, but there are still the dog ears to trim off, right?
