Let's talk feet. I've got the set of 3 right side guides. I use the 1/4" for sewing binding on carpet. I also have a left side 3/16" guide. Comes in handy for the other side of the French seam when the cover is too much to cram under the machine. Also a standard welt foot for welt and a 1/2" welt foot to sew windlace.
