I learned this from the engraving master Jason Machiafava (J. Fava
Engraving). If you have access to, or can acquire, a toner (not ink
jet or laser) printer/copier, make a print of your design. Position
your design on your piece, print side down, and with a cotton ball
soaked in pure acetone carefully soak the paper. Peel the paper off
carefully and your design will have transferred onto your metal and
will stay. To remove when you are done (or if you goofed on these
steps) the acetone will remove the ink.
Have fun!
