I bought my wife a Baby Taylor for Christmas (she hasn't played for thirty years). She uses a pick; I usually don't. She seems to be lightly pinching it between her thumb and pointer so that the pick is almost an extension of her finger; is that all right? When I use a pick, I place it firmly at a right-angle to my thumb.
Another question: can thumb picks be used for upstrokes? I started trying to use them (usually I just strum with my thumb alone), and I haven't had much success with upstrokes? Any tricks, or should I just use the pick for downstokes and single notes?
