Recently, I ebonized a block of birch for a project. I swabbed on the
black leather dye, let it dry, rubbed it in, and finished it coats of a
varnish-boiled linseed oil - turpentine mixture. I'm pleased with the
results.

I tried the same technique on a piece of red oak, and it also looks
good. I plan to try some other colors.
