Tuscany Collection 100% Wool Batting is a very popular choice for both hand and machine quilters. The loft and resilience inherent to the wool fibers allow quilting designs to show off to great advantage. This product is made with the finest superwashed wool that is carded and resin bonded to retard bearding. The superwash process smooths the scales on wool fibers, which makes the wool pleasant to the touch and less likely to shrink. The natural fiber breathes, allowing excess heat to disperse away from the body. The tiny fibers trap air which creates insulation in this lightweight batt. The loft retention is outstanding.
