This works like a traditional silk dye, but is easier to use. It spreads smoothly and easily. Fabrics become radiant, keeping their suppleness and brilliance. You can create unique patterns using water-based gutta resist, salt and sun techniques. All 30 Setasilk colors are intermixable, allowing you to create your own palette. You can also use the Setasilk Thinner to make the colors more pastel. We have found that Setasilk also works beautifully on cotton with our Sabra Silk Resist, as well as on silk flowers and basket reed. Heat setting is recommended for permanence.
