Pack contains 1 piece: 228cm x 274cm (90in x 108in). Heirloom Premium Wool batting provides superb insulation. The fiber breathes, allowing excess heat to disperse away from the body. One of the many benefits of wool is that it gives warmth without adding weight. Wool can absorb up to 30% of its own weight in moisture without feeling damp. The tiny fibers trap air which creates insulation in this lightweight batt. In addition, wool batts are naturally mildew resistant and resistant to moth damage when quilted with cotton fabrics. This batting can be quilted up to 4” apart and has excellent loft retention. Heirloom Wool batting is lightly resin bonded to provide stability and retard fiber migration and bearding. Test if using with dark fabric. Hobbs Heirloom Wool Batting is made of the finest superwashed wool in the world. This batting may be stitched up to 4′′ apart, and it is machine washable (once inside a quilt), with shrinkage of 3-5% expected.
