A bolt is a unit of measurement that counts the number of yards or meters on a single textile roll or bolt. It is an important consideration for furniture manufacturers and fabricators in determining the total material needed for a project. The bolt size most often correlates to the weight of a fabric and can vary greatly. To ship or use for storage purposes, a textile or wallcovering material is rolled backside out onto a tube to protect its integrity, and then wrapped in plastic bags. The tube is wider than the textile to protect its ends. Textile bolts should always be shipped, handled and stored lying flat to avoid any creasing of the material.
