Designed to reduce puckering when embroidering microfiber performance shirts and moisture wicking materials with excessive stretch in the fabric. We recommend the following for best results: Hoop or float a piece of Medium Soft Tearaway backing next to the machine table. Do not strech the garment when hooping and keep hoop level ( do not recess inner hoop). A heat-sensitive product. It is recommended that garments hang to dry. If placed in a clothes dryer, use a short time on a cool setting. Ironing is not recommended. If ironing is required, iron on low setting from right side of fabric only.
