This is a clear thickener that was developed to be used with Setacolor Transparent fabric paint. When you mix it with the paint, it thickens it, while keeping the color clear and transparent, unlike mixing with a thicker white paint, which makes a pastel. It can be used to make Setacolor Transparent thick enough to silkscreen with or stencel with. It can also be used to thicken any other thinner water/acrylic based fabric paint, like Setasilk, Dye-Na-Flow, etc. Add to taste, stirring well, until the desired thickness is achieved. Keep in mind that the more you add, the more it will thin the pigment, and colors can get lighter.
