Dritz brand Dressmaker's Marking Pencil in white for dark fabrics. Water-soluble pencil for transferring straight, curved and embellishment pattern lines directly on firmly woven fabrics. Remove all marks with brush or damp cloth before ironing so marks are not permanently set. Test on fabric to make sure marks can be removed.  Mark darts, pleats and buttonholes on washable fabrics. Since this product is water soluble, best used on fabrics that can be washed, not dry clean only fabrics.
