Dear Nathan,
If you will try the "search messages" function for "Sauce" you will have quite a bit of information pop up:

Peggy is working on an article as well as a sauce video that will no doubt be of great interest to you. Incidentally, I had the chance to watch snippets of a sauce portrait of Vincent Miller, which Peggy did from life at the Portrait Society of America last spring, and it was marvelous. Peggy is a painter who can really "walk the walk!"
