When I wanted one for my FW I found one on the Clotilde web site that fits very good and I like it - can't remember the maker's name. When I was looking for one for my Bernina 440, I found one at the Puyallup Sew Expo at the Dream World (
www.dreamworld-inc.com) booth. They make nice extension tables for any machine. They are known as the Sew Steady tables.
