For use with Setasilk. Thick textured water based Setasilk Gutta can be used for outlining. Pearlize, they are applied directly with a tube or an applicator bottle. They pass perfectly through the fiber of the fabric and stop Setasilk colors, which can be then applied. Once fixed with an iron, water based guttas resist washing except for the clear gutta, which is especially formulated to be removable by washing.
