Darning is a sewing technique used to repair holes or worn areas in fabric, particularly in items like socks or sweaters. It involves weaving thread back and forth across the damaged area to create a sturdy patch that blends with the surrounding material. This method not only extends the life of clothing but also adds a unique, handmade touch. Traditionally, darning was done by hand using a needle and thread, but modern tools like darning eggs can help maintain the shape of the fabric while working. This technique is part of the broader practice of mending, which emphasizes sustainability and resourcefulness in clothing care.
