This fit my low shank Singer perfectly. I bought it because I wanted a certain kind of ruffle and this did the trick; the ruffler foot would have been way more work. If you've never used a gathering foot before, start with a scrap piece of fabric to get the feel of how to use it along with going online to find settings for the stitch length and tension as this will make a difference in how tight your gathering (ruffling) is. As far as people saying that the foot didn't come with tips or instructions... this is true. However, I have bought several different feet from sewing supply/quilting stores as well as online and I have never once received any sort of paperwork with the purchase. I guess the companies think that if you are buying this foot, you must know what to do with it. Definitely go to online resources and you will get more info and visual instruction than you ever could have in a little pamphlet.
