Made from natural Gutta Percha to produce the finest resist available. Resist is used to draw the edge of an image on silk, stopping the flow of dye at the resist lines. With heavier silks, the resists may have to be thinned so it completely penetrates the fabric. Use Jacquard gutta solvent to thin if necessary. The resist should be completely dry before applying dye. Colored guttas should not be dry-cleaned.
