Since the class I took at Sitka, I've been painting mostly with Oils and wax medium that the instructor uses. He gave us all a little of the medium and I had enough left over to do some small paintings at home. I finally ran out and was unable to order more soon enough so I thought maybe I could make my own. I was able to get bees wax and Alkyd. I grated the bees wax and mixed it with mineral spirits until it softened and then I added the Alkyd until it looked right. It felt and looked just like the stuff that we used in class. The real test will be how it dries and whether or not it flakes off.
