Gutta Silk is a relief liner specially for creating 3D lines on silk and, once dry, protects the colours from flowing into one another. The relief liner is available in 3 colours and 1 Gutta Silk masking fluid. The masking fluid is applied before the Textile Silk is used, thereby repelling the paint on areas where it is applied. The masking fluid is washed off with water. The coloured relief liner, once dry, can be fixated by ironing.
