I'm taking a foundation diploma at a residential art college in the South of England (it's 10 short courses over two years, so I go there for 3-5 days every couple of months) and my last course was "letter cutting in stone and slate" taught by Tom Perkins. If you've not come across his work, look him up - his work is exquisite.
I've not done any stone carving before, beyond a couple of hours a year or so ago, and a very brief go when I was about 10, so I'm quite pleased with how this has turned out, though I can see so many things that need improvement. Mostly down to familiarity with the tools - I have no finesse with the chisel. That should come with practice though.
First drew up the lettering on paper, then transferred that to the slate with white watercolour pencil

I'm looking forward to getting my own tools & some scrap slate to practice on. It's a very different experience to pen & ink work, but is really satisfying.
