abstract:
A bolt is a unit of measurement used as an industry standard for a variety of materials from wood to canvas, typically materials stored in a roll. The length is usually either 40 or 100 yards, but varies depending on the fabric being referred to, for example, a bolt of canvas is traditionally 39 yards.
