Sew Stable will stabilize fabric before machine embroidery. By stabilizing the fabric with Sew Stable, you will eliminate the need for a hoop. Sew Stable washes out completely when the embroidery is completed. Sew Stable stiffens the fabric jsn't enough so that the needle can still penetrate the fabric easily but, without puckering under the sewing machine foot. Ideal for garments where a backing would show through the material.
