Stitches are the basic building blocks of sewing, used to join two or more pieces of fabric together. They can be created using a needle and thread, and come in various types, such as straight, zigzag, and decorative stitches. Each type serves a specific purpose, from simple seams to intricate designs. In sewing, the choice of stitch affects the strength and appearance of the finished product. For example, a straight stitch is commonly used for seams, while a zigzag stitch allows for stretch in fabrics. Understanding different stitches is essential for anyone interested in sewing, whether for clothing, crafts, or repairs.
