Burlap is a type of fabric made from natural fibers, such as JUTE, HEMP, and GUNNY. It is often used to make SACKS and COARSE cloth. JUTE and HEMP are the most commonly used fibers for burlap, with GUNNY being a less common alternative. The term 'SACK' is also used to refer to a bag made from burlap, while 'JUTE' and 'HEMP' refer to the fibers themselves. Burlap is a versatile material that can be used for a variety of purposes, from making bags and SACKS to creating clothing and home decor.
