Etching on copper

Again with the pennies!!  After flattening a few pennies, I drew a freehand design on each of them using a red Sharpie (quick and simple - just experimenting!) then put them in the etching solution for about 40 minutes.

ferns and such (remember, freehand) - etched and patinaed with gun blue.

big old swirl, etched; then I added a "heart" <3 using my stamps; patinaed.

flowers and stems - this one was etched twice - once for 30 minutes, then again for 20 minutes; also patinaed.
