My first tooled piece. Picture of fish tooled on 26 gauge aluminum. Once embossed, I colored in some of the lines with permanent marker, lightly sprayed the whole piece with isopropyl alcohol, then gently wiped it with a paper towel. Spraying it with alcohol made the colors blend together and reach all the recesses. Blotting/wiping it with the paper towel left the fish with even more texture.
