Another question on appliqueing squares. After a 2" sq is folded under with mitered corners now a 1" sq, how are you keeping the corners together. I have been stitching each little mitered corner with a couple stitches. Only problem is I have 120 squares to do. Can't applique each one at a time. Have to wait till 11 are done to do an even row across. Is there another way to keep corners together. Is there a spray or something. Could use help before I get too far along. If tacked about 20 so far. Thank you in advance.
