Quilter's Dream Puff's special silky soft fibers are 1.5 times warmer than down and 2x warmer than most high loft polyesters. The loft is between 1/3-1/2" yet very light in weight. Fibers are carded, crosslapped and thermally bonded. Stitches up to 10" apart. May be machine washed and dried, it will not shrink or crease. Excellent for hand and machine quilting plus tied quilts, trapunto, comforters and wearables. Can be easily layered for even greater loft. 122" x 120"
