With the Featherweight you are in luck, it takes general low shank feet and attachments. Accessory boxes for a 15, 66, 99, 201, and other straight stitchers will generally work. There are a few exceptions like cover for the feed dogs and possibly darning feet that needs to be especially for the Featherweight. On fleabay there are often bundles of feft and attachments, they can be a goof buy. The bobbins have to be especially for the Featherweight, very few other models take this type. The buttonholers for the old straight stitchers are very nice. Some of the zigzaggers are better than others.
