Altho the FW is a simple straight stitcher, they made attachments for everything, even a zig-zag attachment. It used to be really easy to pick up rufflers, tuckers, hemmers, those round hemmers, buttonhole attachments, etc. at thrift stores. I've not found any lately, but don't get to the stores like I used to.
Our last road trip, I actually found a period walking foot, called a penguin, in the box, with the instructions. I haven't tried it yet, but I'm about ready to get her out and play with all those attachments! They really could do almost anything we can.
