I am working on a kids game. Memory blocks. I have embroidered different pics on little 2 inch squares. My bad, they should have been larger. Anyway, I don't want them to go to waste, so am zigzagging around the edges to hold the front and back fabrics together. Doesn't look too bad, but my corners keep hanging up down under my foot. Is there a trick I can do to keep that from happening? Seems like I saw something one time, but for the life of me, I just can't remember.....any ideas would be greatly appreciated.
