Ah yes Cas, but remember what Shakespeare wrote, "One may smile and smile, and be a villain."
On the bleeding of dyes, it is true one must be careful, they are really thin and will sneak about a bit. I'm new to using them
myself after having such poor results with commercial stains. One thing I like to do is dye a large area, coat it with sanding sealer,
then cut a design through the sealer and wipe the dye into the design so it will wipe off of the surrounding area. Also, the dry brush
technique that artists use is useful. Of course if you do unrealistic things like I do nobody knows if you screw up the colors! When I was recording music we called them happy accidents.
