The Rain City Engravers are doing a group project this year, printing a calendar for 2011, with engravings done by various members. Marya and I are doing August. We each did an engraving; while hers requires several passes, mine was quite simple: a cockle shell. Here's the engraving (on a Resingrave block), locked up with the calendar (in magnesium), and inked.
Ready to print
Done!
Here's three of them. My share was 65, which took about 3 hours.
I can recommend a cockle shell as a great first engraving project; it was much easier than any the other engravings I'd tried before.
