Sewing machine inserts are designed to fill the gap left by machines when they are stored in the "flat-bed" or "flat" sewing position (when the needle plate is flush with the surface of the cabinet) on three-position or variable position cabinets. When ordering, we need to know the machine brand name and model number in order to ensure the proper fit for your cabinet and sewing machine. Text entry boxes are provided in the shopping cart for this purpose, so don't forget to write in your information!
