Pellon Wool Polyester Blend Quilting Batting off-White 96 x 30 Yards by the Bolt - 1 Pack. It is made from super soft Wool and Polyester. 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 when used in projects for that season. The softness of this lightweight wool batting for quilt 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. By the Bolt / Off-White 50% Wool / 50% Polyester
