backing

Backing is the name for the fabric used on the bottom layer of a quilt sandwich, or the “back” of the quilt, the part that is usually not displayed. Typically a backing is referring to the fabric used for the back of a quilt while the quilt is under construction, whereas once the quilt is finished it would just be called the quilt back. While a backing can be created from any size fabric, there are specially made quilt backings that are 108” wide to provide a single sheet of fabric for the backing with no seams.
