The chain stitch is a type of embroidery stitch that creates a series of looped stitches resembling a chain. It is commonly used in sewing and crafting to add decorative elements to fabric. The stitch is formed by pulling the thread through a loop, which creates a continuous chain-like pattern. This stitch is versatile and can be used for various applications, including outlining shapes, creating borders, or filling in designs. It is often employed in hand embroidery and can be done with different types of thread, making it suitable for both beginners and experienced crafters.
