No Flow is an antifusant that will inhibit the spreading of dyes on fabric. It is particularly useful for drawing or writing with dye filled felt tip markers, fabric pens or brushes (with liquid dyes or paints). No Flow dries clear and rinses out with warm water. Apply No Flow with a brush or sponge to the entire area you wish to write on or paint. When dry, apply colors using the technique of your choice. Using No Flow for a signature or logo creates crisp, clear letters or images. After paint or dyes have been set, rinse No Flow out of fabric to restore original softness.
