Interlining

Interlining is a layer of fabric inserted between the face and the lining of a garment, drapery, or quilt. It is similar to batting, a thick layer of fiber designed to provide insulation, loft, and body to quilts, pillow toppers, and heavy winter jackets. Depending on the application, the materials in this layer can be woven, knitted, or created by fusing fibers together. Silk, wool, and artificial fibers with good insulating qualities are common choices for interlining.
