Directions: Always check for colorfastness in a hidden area before using. Shake well. Cover work area with a cloth. Brush hat to clean surface. KAHL'S HAT STIFFENER IS ONLY TO BE APPLIED TO THE BOTTOM RIM OF THE HAT. Spray fine mist over entire area holding the bottle 8”-10” from the hat. Allow to dry. Use steam to reshape hat to desired style. ( A pot of boiling water can be used for steaming, hold the hat over the boiling water to use steam to push the product into the fibers.) Repeat above procedure if more body is desired. If you do not steam this product into the hat it will sit on top of the fibers and leave a residue that will chip and flake. Steaming is a priority. Do not saturate, instead follow the procedure a few times.
