E - 80/20 Cotton/Polyester Batting With Scrim - Needle Punched is a soft, durable and substantial batting created for quilters who want cotton with the added benefit of wash-ability and good stitch definition. It is made of 80% ultra Clean Cotton and 20% Polyester with a scrim binder that allows for stitched areas up to 8-10" apart. It has an expected shrinkage of 3-5%. It has a soft loft, creating less resistance when hand quilted and a soft, quilted finished look. Hand, machine, and longarm quilters all love this blend.
