Quilters Dream 80/20 the perfect blend of 80% high grade long staple USA cotton fiber paired with 20% fine denier poly microfiber for a soft, silky batting that drapes beautifully and breathes well. The long staple cotton fiber reduces shrinkage and adds stability so that the stitches can be up to 8? apart. The poly micro fibers add loft and resistance to creases/wrinkles. Our proprietary blended fibers are specially carded, cross-lapped, and needle-punched for strength, consistency, and a beautiful soft drape. There are no scrims, glues, or other binders to resist the needle, so this fine batting can be hand or machine quilted with ease.
