I use Sharpies to color my Corn Cob pens.A trick I picked up is the sharpie will color the blank semi opaque ginig it a "painted" look.I blend the color(S) with a rag and some DNA.
When I get the color or effect I want I set the color with BLO.
CA will have a tendency to alter the finished color but give an interesting effect at times.
I just finished a pen for my son's music teacher. It is made of stabilized saguaro cactus. When I tried to dye it blue, the dye didn't work well because of the stabilization. I grabbed my blue sharpie and it worked amazingly well. I finished off with CA and the pen finish is exactly what I was looking for. I have no doubt that it would work as well on unstabilized wood. The only problem is that the marker does not put a delicate or subtle color down. My blue pen is blue!
Jim,
(great name by the way!)...if you actually went out and tried it, then my answer is probably already too late, but...yes, right on the wood. It (obviously) works better with lighter colored woods.
James, let's see some pics! Like Eagle says...no pics, it didn't happen.
