Heat2Go, from OESD, is an iron away topping/stabilizer perfect for use on delicate fabrics. Fabrics must be capable of withstanding iron temperatures between 260 °-300 °F (120 °-140 °C). A topping is used in combination with a stabilizer to prevent piled fabric from pushing through your embroidery design. Where a stabilizer is used on the bottom of your fabric, a topping is applied above your fabric. After embroidering, simply iron away the excess Heat2Go Topping. Ideal for us with corduroy, towels, fleece, and other piled materials. Each roll of Heat2Go contains 10 yards of 9-inch topping.
