Pellon Wool Blend Quilting Batting White. 120 x 30 Yards by the Bolt / Roll. It is made from super soft thermal-bonded wool. Wool breathes naturally and allows air to pass through making it a wonderful material for summer quilts and garments. It also has qualities that can help provide warmth in the winter. The softness of this lightweight wool quilt batting is ideal for machine quilters who desire very closely stitched areas. It remains soft and does not result in a stiff quilt when using a finer thread.
