Hi, I have tryed the curve master presser foot. I does work, and the bent tip tweezers are great help I would not try to use it without them. Regular straight tweezers aren't very helpful .I have also found another method fpr piecing curves taught by Nancy Elliott MacDonald in her book Winding Ways Quilts. The way she teaches I don't even use the curvemaster anymore. It depends a lot on how you cut your fabric and which piece goes next to the presser foot when you sew. I have taught beginers this method and even they can sew curved pieces with a little practice.
