Pat writes to us: I purchased this Johnny Beard bellows and then did a Pen Work design on it. This is accomplished by drawing the design and then filling in the negative areas with ink applied with a Rapidograph pen. Since this was to be hung by a fireplace or wood stove it needed to be protected from the heat. I applied Permalac as the final coating. It has held up and I have since used Permalac on many of my projects.
