Our 40 wt. glazed cotton hand quilting thread glides smoothly through fabric without tangling or knotting. Made from 100% Egyptian-grown extra-long staple cotton and coated with a thin glaze that helps reduce breakage, shredding, and lint. Each spool contains 500 yards. Quilters love its smooth texture, consistency, and durability to withstand repeated needle pulls across a variety of stitching techniques, including backstitches, running stitches, stab stitches, and more. Due to the glazed coating, this thread is not recommended for machine quilting.
