I rarely experiment with different types of media these days. After finding one medium I was comfortable with (acrylics) I've pretty much stuck to that. But I discovered (by accident) a few days ago that a set of toned drawing pencils which I bought years ago are actually water soluble. So that's what I've used as a partial 1st layer here- drawing with the pencils and then using a brush and water to blend it. I may end up painting over parts of it, but it has an effect that I like so far.
