Quilting is a sewing method done to join two or more layers of material together to make a thicker padded material. A quilter is the name given to someone who works at quilting. Quilting can be done by hand, by sewing machine, or by a specialist longarm quilting system.

The process of quilting uses a needle and thread to join two or more layers of material to make a quilt. Typical quilting is done with 3 layers: the top fabric or quilt top, batting or insulating material and backing material. 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. A rocking, straight or running stitch is commonly used and these stitches can be purely functional or decorative and elaborate. 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.
