Those look really nice Jack. I just picked up a couple of those pens yesterday and will try them out this weekend. Hope my results are as good as yours.
Strong work Jack! Could you post the marker #'s here so we know which color you used. They have so many shades that it would be nice to see which color is which. Did you do anything different than my method?
I, like JimGo, got a set off Ebay. I got a set of 24 for less than $20 shipped. Much better than the price you find in the stores or buying one at a time.
