Griest made all sorts of machine attachments even for Singer before they branded their own. Your buttonholer works just like the Singer one and they are great because every buttonhole is uniform and identical. I use my ancient old buttonholer on my Janome 6500 because its buttonholer can't handle larger or thicker buttons. These old buttonholers will fit most short shank machines. My second hand store sells buttonholers for $5.00. They are common as most vintage machines seem to have one. If you want to FM quilt and your feed dogs won't drop you can use the buttonholer feed dog plate to cover them. Works like a charm.
