I have been working on learning FMQ. Doing pretty good and liking it, but I have been using the open embroidery foot...and have seen it said many times to use the walking foot. I thought the walking foot was for thicker layers of fabric, but although you are stippling FMQing through layers...isn't there the feed issue that you would not want for the FMQ but do want for the layers to sew through? Or do you lower feed dogs with the walking foot...and then..whats the point of hte walking foot over the open embroidery foot?
What's the diff and which do you like?
