Hobbs Heirloom Premium 80/20 Bleached Cotton Blend Batting is highly recommended for use when working with white or very light colored quilts. The bleached 100% cotton fibers, combined with the fine, white polyester fibers, provide a very white batting that will keep quilts made with white or light-colored fabrics nice and bright. Whether you're creating a utility quilt, a quilt to give as a gift, a household decor item, a wall-hanging or a show quilt, this batting should be considered for its strength, durability, color, loft and finish. Quilting/stitching should be every 4" inches, or closer, and quilters may experience shrinkage of 3-5%. Pre-washing is not recommended for this or any of Hobbs other quality batting products.
