Batting is the layer of fiber between the backing and the quilt top. Batting offers warmth, softness, and texture to the quilt. The type and amount of batting helps determine the thickness, stiffness, and drape of the quilt. Cotton batting, for example, offers softness and durability. While wool batting tends to hold the quilt’s shape and offer warmth, polyester can give more loft or thickness to your quilt without added weight. Batting can be purchased in standard sizes to make twin, queen, or king size quilts or you can cut batting to fit your own project size.
