Chain stitch is a type of embroidery stitch that creates a series of connected loops, resembling a chain. It is commonly used for decorative purposes in sewing and can be worked by hand or with a sewing machine. The stitch is versatile and can be used on various fabrics, making it popular in both craft and fashion projects. To create a chain stitch, the needle is threaded and passed through the fabric, forming a loop. The needle is then inserted back into the fabric, pulling the thread through the loop to create the chain effect. This stitch is often used in textile art and quilt making.
