Fabric fastener is a term used to describe any type of material used to secure two pieces of fabric together. One example of a fabric fastener is Velcro, which is a brand name for a hook-and-loop fastener. It consists of two strips of fabric, one with tiny hooks and the other with small loops, that attach to each other when pressed together. Velcro is a popular choice for clothing, shoes, and other items because it is easy to use and can be opened and closed multiple times.
