Batting is made with fine 100% USA cotton. It is then carded, and especially needlepunced to prevent bunching/shifting and is completly washable. It will shrink 3-5% like all needlepunched 100% cotton batting. It can be quilted upto 4" apart. Bleached cotton should be used with light or white fabrics to eliminate the shading of darker battings. 120" X 120"
