I almost forgot to mention that I met the woman who developed the curvemaster foot. She was demonstrating it's use. I'm getting ready to make a quilt with lots of curves. I tried a sample and just used my regular 1/4" foot. I tried the method I've seen on U-Tube with no pins or clipped seams. It worked just fine but after seeing her demonstrate the foot in person and explain why it works I decided to pay the price. I'll let you know if I think it's worth it. The reason it is supposed to make the job easier is because the front of the foot is much shorter and closer to the needle.
