Remove stone & saturate felt cushion with ink. Prime the stone by adding ink to only one side of the stone. Put stone back in container with the inked side facing the inked felt. Capillary action will force the ink to the surface of the stone. If not, add more ink to the felt only, NOT the stone. If the stone is over inked, blot excess from the stone surface with a clean, lint-free towel or cloth. Add ink to felt only when the impression becomes faint.
