Thank you, Tammy.

Yes, wiping out is the beauty of this medium, from what I can tell so far. The surface is incredible forgiving, so you can really adjust values readily, just like you can in a charcoal portrait. Sort of the "make a line, break a line" concept. With the second, mineral spirit, erasure, you can almost restore the white of the canvas, just by lifting the color.

I should be so lucky to "nail" everything the first time!

Oh, by the way, I have used water-based oils to paint before and I greatly dislike them.
