A patchwork quilt is a quilt in which the top layer may consist of pieces of fabric sewn together to form a design.[1] Originally, this was to make full use of leftover scraps of fabric, but now fabric is often bought specially for a specific design. Fabrics are now often sold in quarter meters (or quarter yards in the United States). A "fat quarter" is one square meter (or one yard by the width of the fabric, typically 42–44") folded into four and cut along the folds, thus giving a relatively square piece of fabric 50 cm on a side, as opposed to buying a quarter of a meter off the roll, resulting in a long thin piece that is only 25 cm wide.[1]
