A drawcord (or drawstring) is a versatile cord, string, or ribbon threaded through a channel (casing) in fabric that allows you to gather, tighten, or close an opening, commonly used in clothing like hoodies for adjustable hoods, waistbands, or bags for securing closures. Made from materials like cotton, polyester, or elastic, it can be round, flat, or braided, often finished with plastic or metal tips (aglets) for easy handling.
