From Cotswold Industries

RinseAway, a water-soluble topping offered by Cotswold Industries, can be used to keep embroidery stitches from sinking into high-pile terry cloth or textured, ribbed corduroy. This invisible film creates a smooth surface that supports stitches and allows for crisp definition and detail, according to the company. RinseAway is hooped along with the fabric and stabilizer. Once sewing is finished, excess can be torn away and remnants are easily dissolved by lightly spraying the design with water, dabbing with a damp cloth or lightly steaming with an iron.
