DECOLA washable reserve is an aid in silk work. Transparent reserve is designed to prevent the penetration of paints into the fabric in the places where it was applied. It does not allow colours to mix with each other on the fabric (in separate areas that are limited by the contour). Applying the reserve and letting it dry, paint is applied to the fabric. After the product dries, the pattern is fixed with the iron from the inside. After cooling, the product is rinsed in water or washed, while the reserve is washed off. The reserve is available with a convenient thin tip in metal tubes (18 ml).
