You live in California buddy?
I don't think there's much to it? Get a laise chair and lay outside during the day, if its hot out you should wear a sun screen of about 15 to 25 depending on your skin type.
You can sun in the channel, next to the pool on the beach; it doesn't really matter as you mostly close your eyes while sunning?
I don't think your wife really needs lessons for it?
(hee, hee, couldn't resist)
