Congratulations on becoming the proud owner of a featherweight. Shame on your friend for even thinking of throwing it out. So glad you were there to come to the rescue. My FW came with lots of accessories and I've also purchased a few feet that I thought would be useful. I don't like either of the 1/4 inch feet that I bought as well as the one that came with the machine. I also have a free motion foot that I bought on a whim just to try FMQ but haven't really used it for anything yet. I'd suggest that you get her cleaned up and oiled, then give her a good trial run by piecing several blocks. You may find you don't need a lot of accessories or extra feet. BTW, you can download a 221 manual at
