Seals the back of waterproof fabric after machine embroidery. Embroider on waterproof or water-repellent fabrics without compromising their waterproof properties. Just apply Stitch 'n Seal to the back of your embroidery - water and moisture will not penetrate the fabric through the tiny embroidery needle punctures. Use our Stabilizer Selection Tool to find the correct combination of backing and topping for the specific technique and fabric on which you are sewing.
