With this painting, I'm trying a couple of things that are out of the ordinary. For one, this painting is being done on polyester, not cotton or linen. Polyester does not stretch out like cotton, and is not affected by temperature and humidity like cotton and linen, and it lasts much longer. When conservators re-line an old painting, they use polyester now. So far, I really like it. The canvas is as tight as a drum, with a lot of spring to it, and is as tight after two days of work as it was in the beginning.
The other thing that's different is that I'm painting with a painting knife instead of brushes. Painting knives are kinda like small, narrow trowels. I wanted a very energetic paint surface and you can certainly get that with a knife. This isn't a tool I'd normally use, and probably will not use very much after this, but it's different and fun, and it's good to get out of your normal routine every once in a while.
So now it's off to the studio. Got a lot of work to get done and not much time to do it in.
