Legacy Wool Blend Batting is made from super soft wool. It is thermal bonded to prevent bearding and will shrink 0 to 3 percent. Wool breathes naturally and allows air to pass through making an excellent summer quilt. It also has qualities that provide warmth in the winter.

When using a finer thread it soft and does not result in a stiff quilt. Thermal Bonded 50% Wool 50% Polyester. Ideal for hand and machine quilting.
