Dye-Na-Flow Fabric Paint is a free flowing, concentrated liquid colour for use on any untreated fabric. It will spread on fabric until it is thoroughly absorbed and even. Every fabric has a different flow and spread. It is magical on silk, but it works on any type of fibre, natural and synthetic. Dye-Na-Flow is incredibly versatile. It is perfect for silk painting including the serti technique with resist, spray on tie dye, watercolour, airbrushing, salt technique, spritzing through stencils, sponge printing and simplified batik or wax resist effects. Dye-Na-Flow can be used in place of Procion Dye for tie dyeing. Dye-Na-Flow requires heat fixing by ironing or being placed in a clothes dryer.
