This was just on Fons and Porter today. Liz Porter was the guest and Mary Fons was the host. Liz showed Mary a trick. She said make sure the top seam is pointed towards the machine and the bottom seam pointing towards you. That way the machine pushes the seams together forming a perfect point. She had Mary sew several together in chain piecing and all the points were perfectly snug together. They were sewing little four patches.
