The velvet is made substantially of cellulosic yarns and the dye is cellulose specific. The finishing solution and fixer are applied, if a sheen is desired, then the dye is applied by brushing the item with the applicator tip until the dye has saturated the item and is used up. The item is allowed to stand at room temperature for at least 24 hours for the dye to set. Bleaching the dye from the item with a reducing agent prepares it for re-dyeing.
