Tacky back, no shadow through lightweight fabrics. For hand embroidery, apparel & appliqué. Supports 8000 stitches. Embroidery stabilizers are used as a backing on your fabric in order to allow your project to finish well without pucker or slipping. In order for a well formed stitch to be created the fabric must be stabilized. The softer your fabric the more need for a stabilizer. This also is true for designs with higher stitch amounts.
