Thread sketching can add lots of texture and movement to your quilts. But as anyone who has tried it knows--if you don't stabilize your work, your fabric will draw up and pull out of shape.
I love the soft shimmer of metal embellishment on a quilted surface. Just a touch of metal can act as an elegant focal point. An all-over quilting pattern of metallic thread, couched wire, or foil can add texture and make the quilt seem to glow from within.
