Horn Flatbed Inserts & Insets are replacement or additional flatbed surfaces for Horn sewing machine cabinets, available uncut as a filler or lightbox, or cut to fit a specific sewing machine model. Because insert and inset sizes vary across cabinet models, please have the following information ready when ordering: the make, brand, and model number of your sewing machine; the length and width of the aperture in the cabinet top; and whether you need an insert (with a lip) or an inset (no lip). If you're unsure, contact Quilt Direct before ordering and we'll help you identify the correct size. Shop Horn flatbed inserts and insets at Quilt Direct.
