The process of mending a hole in a woven fabric is called darning. Darning involves interweaving the threads of the fabric with a needle and thread to fill in the hole and create a seamless repair. It is a traditional method of repairing fabrics, often used for repairing socks, sweaters, and other knitwear. Patching involves adding a separate piece of fabric to cover a hole, while crotcheting is a method of creating fabric using a crochet hook and yarn, and sanforizing is a process of pre-shrinking fabric to prevent it from shrinking further during use.
