A quilt is a type of bed covering crafted from two layers of fabric with plush padding in between, called batting. The bottom layer, or backing, is typically a single piece of fabric. The top layer can be constructed from one fabric piece or, in the case of a patchwork quilt, from many pieces of fabric in different colors and patterns.
The top and bottom layers are connected by decorative stitching, which often forms geometric patterns in the fabric. Called "tying," the stitching process passes through all three layers of the quilt, so that it holds together durably. Though you can buy quilts in stores, making quilts by hand is also a very popular hobby.
