HST using a diagonal cut square
I am starting a pattern that is made up of HST's and the maker of the pattern uses a large square that you layer the two fabrics together, sew a 1/4" seam all the way around then cut diagonally from corner to corner to make 4 HST's. Of course, this is going to make them all bias edges.
What is the best way to handle these HST's without pulling them out of shape? I have starched the fabric, but what else can I do?
Thanks, Watson
