The ultimate slippery surface for free motion sewing. Eliminates the drag on your free-motion sewing and quilting projects. The sheet has a non-stick top surface which is bonded to cured silicone with a tacky back that holds it to your machines surface - no tape required. A generous 12'' x 18'' with a precut needle hole (1'' x 1.5'') that fits most sewing machine beds, can be cut with scissors if needed.
