It’s the technique that involves covering the figures with a layer of light fabric such as chiffon, organza or tulle that will shadow the background and make the appearance less sharper. The transparency of the upper fabric gives the figure colors an exquisite air. The quilting made topmost, either with the applique colors or with silver/golden threads, will sharpen the figure shapes down under, but the figure colors are blurred.
