I bought one several years ago (new item then, I think) and it was partnered at that time with lovely pinpoint tweezers, an aid to feeding your curved fabrics into the foot. I use the tweezers often, especially when I'm doing machine embroidery ... they're ideal for grabbing little thread ends that need snipping off in areas where my fingers won't fit. I just found the curve master foot available at several suppliers, but not together with the tweezers anymore. They're sold separately now. I only used the curve master foot a couple of times to see it it works and it does seem to.
