Hi R.,
I am in Boise also....
I learned how to Faux finish walls through trial by error. I went to Home Depot and asked alot of questions bought a book and found a wall that I could practice on. It took me a few tries but I finally got it right. It was alot of fun
As for oil painting good luck...:) Try looking at a crafts store to see if they have some ideas or online for how to guides.
