Pellon® SF101 Shape-Flex® is an all purpose, woven, fusible interfacing.  It provides crisp support for collars, cuffs, yokes, pockets, facings and other detail areas of a garment. Very popular to interface fabric for use in bag making. By Annie suggests using it in all of their bag and tote patterns as it gives a lovely feel to the fabric making it easier to sew.

It can also add body and permanent stability when used as a backing for needlework and punchneedle embroidery. Shape-Flex® is intended for light to medium woven and knit fabrics, including oxford cloth, chambray, gingham, madras, tattersall, pincord, flannel and polyester/cotton blends. To pre-shrink, fill a sink with warm water.  Place interfacing in water for about ten minutes.   Do not put in washer or dryer by itself or you may loosen the adhesive.  Gentle squeeze out excess water and allow to dry.
