After applying paintstik color, allow the painted fabric to dry for 3-5 days, and then heat-set to make the colors permanent.
To heat-set the color, set your iron to the proper setting for the fabric. Place an old piece of fabric or muslin on your ironing surface, put the fabric paint-side down on the muslin and press for 10-15 seconds in each spot. The muslin should absorb any excess oil that remains in the paint.
Warning: If you have not allowed sufficient drying time, you will drive oil into the muslin and probably into your ironing surface. If you must heat-set your paints before they are completely dry, put a piece of greaseproof paper (such as parchment paper) over your ironing surface to prevent staining.
