My oil paints have been sitting in a bin for quite a while and in danger of turning into petrified blobs. I think the last time I actually used them was at a workshop I took with my art pals, Judy Mackey and Nancy Medina.
When I was in college (back in prehistoric days), I painted exclusively in oils. Acrylics were horrible and difficult to use. But, over the years, acrylic paints were perfected and I found that I preferred them over oils. However, that old bin of semi-dried out tubes were beckoning to me.
I started this painting in my usual manner. After slathering on molding paste to create texture, I underpainted in acrylic but wasn't able to get the blending effect I was striving for. I dug around in the bin and found several tubes that were still in good condition. I had forgotten how much easier it is to work in oils as compared to acrylics. Don't get me wrong, I don't intend to switch completely to oils but at least now I know that I can use them together when I need to. Just some words of caution, in case you're planning to do the same. Oil and water do not mix! Always paint fat over lean - oils over acrylics.
