I pretty sure one of the vintage low shank zigzag attachments will fit the 15-91. I have one that fits my Featherweight, haven't tried it on the 15-91 but I don't see why it wouldn't work. It's fun to watch because the attachment moves the fabric side to side instead of the needle to create the zigzag!
