Sulky Soft n Sheer Extra stabilizer is a fusible version of our Soft n Sheer stabilizer. It is an acid free permanent, medium weight, textured, iron-on, non-woven nylon that is ideal for dense embroidery designs. Excellent stretch resistance eliminates pulling or sagging for the embroidery design during stitching and remains with fabric for continued stabilization through laundering and wearing. Packaged in a re-useable clamshell storage container to keep your stabilizer fresh and usable for years. All Sulky stabilizers are acid and lead free!
