A quilt is a multi-layered textile, traditionally composed of two or more layers of fibers. Commonly 3 layers are used. These layers include a woven cloth top, a layer of batting or wadding, and a woven back combined using the techniques of quilting. This is the process of sewing or combining the three layers together in order to reinforce the material. Stitching patterns can be a decorative element. A single piece of fabric can be used for the top of a quilt, but in many cases the top is created from smaller fabric pieces joined together, or patchwork. The pattern and color of these pieces creates the design.
