Jacquard Green Label Silk Colors are true dyes, not thinned pigments, so they do not stiffen the silk or cover the luster. They are used to dye silk & wool. All 20 colors may be blended together into an infinite range of colors or diluted with water for pastels. These simple to use dyes are lightfast, odorless, non-toxic, contain no alcohol and can be hand washed or dry cleaned. They can be set using our Dye Set Concentrate or for maximum brightness by steam setting.
