The process of quilting uses a needle and thread to join two or more layers of material to make a quilt. The quilter’s hand or sewing machine passes the needle and thread through all layers and then brings the needle back up. The process is repeated across the entire area where quilting is wanted. Rocking, straight or running stitches are commonly used with these stitches being purely functional or decorative. Quilting is done to create bed spreads, art quilt wall hangings, clothing, and a variety of textile products. Quilting can make a project thick, or with dense quilting, can raise one area so that another stands out.
