On a side note, I have also been introducing Epoxide Oil from Natural Pigments into my darks. It helps quite a bit with sinking in, and is far more soluble and fluid than Stand Oil.
Now that I have your attention, I also wanted to shamelessly plug my workshop in Whidbey this summer. Remember, I don't get paid for this blog (you vampires) so it's a great way for me to get paid for a week of hearing myself talk. I will also reveal to those taking my workshop how to make my super secret painting formula....ok, it's linseed oil, happy.
