Deka Silk clear outliner penetrates the fabric to create a barrier to prevent dye colours and paints from running into each other while painting on silk. Apply outliner to silk and allow to dry. Paint with silk paints, leave to dry and heat set with an iron. This clear, water based outliner washes out of the fabric once the paints have been set.
You can decant the outliner from these 50ml jars into applicators bottles for which you can add a nib for application.
