Organ's Top-Stitch Needles are used to create decorative top stitching on various materials. The 130/705H (HAx130N) needle system is compatible with most home sewing machines. These Top Stitch needles have an extra long eye that handles thicker threads for top-stitching and deco-stitching, including some two thread stitches. Please consult your sewing machine's instruction manual for compatible needles.
