I just took a FMQ class yesterday. The embroidery foot was one of the ones the instructor said to try. Basically, there's lots of feet you can use, darning, open toe, embroidery. Some folks say that a larger foot is better, some swear by a small one. plastic vs. metal, open vs. closed etc. Try 'em all and then just use the one that works best for you. This is not a one size fits all.
