I used an old pattern to make a cover for my 201. Altered the pattern to make it fit my serger. Next I'll resize it to make a similar one for my FW. I used pre quilted fabric, added narrow bias tape and machine embroidery to the pieces before I sewed them together. Pics are at the bottom of this page:
