Sulky Soft ?n Sheer stabilizer is an acid free permanent, lightweight, textured, non-woven nylon that has excellent stretch resistance and is ultra-soft next to your skin. It provides great permanent stability to stitch on lightweight knits and woven fabrics. Excellent stretch resistance eliminates pulling or sagging of the embroidery design during stitching and remains with fabric for continued stabilization through laundering and wearing. Easy removal once stitching is completed, remove from hoop and cut away the stabilizer up to the outer edge. All Sulky stabilizers are acid and lead free!
