I have the set of Creative Feet and I absolutely LOVE the satin-edge foot for piecing........I can stay with an EXACT 1/4 in seam, or adjust it slightly for those ever so elusive SCANT 1/4 in seams.............I picked mine up at the Quilt Expo last year..........and I think they have been more than worth the cost.............She also guarantees these........so if you get them, try them, and are not happy, you can return them........check out her website....Hope this helps!!
