Deka Silk paints for painting on finely woven natural fabrics and particularly silk. The large choice of mediums and gutta outliners complete the range. Heat set with an iron.
This fluid paint will spread when it touches the fabric and the flow can be more controlled by first treating the fabric with an anti-spread primer. Another method of controlling where the paint goes is to use a silk paint outliner. The outliner penetrates the fabric to create a barrier (or resist) for the paint. Use the outliner to outline elements of the design, ensuring there are no gaps in the outline, allow to dry and then apply the paint within the outlined element.
