Echoing, or echo lines, are lines of stitches sewn at close, regular intervals around an object or shape on a quilt to add texture or to fill space between objects on a quilt. The echo lines follow the shape or curve of the object, emphasizing the negative space around the shape. Echo lines are often sewn by hand in a color of thread that matches the fabric the lines are sewn on. In this way, they add texture without necessarily adding color. Echo lines can also be used to create the motif of a quilt on their own, when they are sewn from an embroidered shape rather than from an applique or other quilt component.
