So strong that you can quilt as closely as you would like or as far as 8" apart giving you great freedom of quilting design. Quilter's Dream special manufacturing process prevents shifting and lumping. Dream Cotton has a very high thermal value (R=3.8) and is warm in the winter, yet wicks moisture away from the body to keep you cool in the summer. With 100% natural environmentally friendly cotton, Dream Cotton Batting proudly bears Cotton Incorporated's black seal. Because there are no scrims, glues, resins or binders, not only does Dream Cotton retain a beautiful drape, but your hand and machine needles will glide smoothly through this fine, consistent cotton batting. Your finished quilt may be machine washed and dried. Prewashing is not recommended as Dream Cottons is exceptionally free of cotton seed remnants and shrinkage is minimal.
