The past couple days I carved a small sample woodcut (from birch plywood). It was not difficult, just time-consuming at approx. 40 minutes per rotunda gothic letter.
I was pleasantly surprised to learn that thin curved lines are actually not so difficult to do with woodcut, but maybe not thin enough for Spencerian. This makes me think a bit beyond my earlier plan and consider baroque italic. The wood grain interferes with fine carving less than expected.
