Well, I have no problem with natural (left hand) or artificial (right hand) harmonics, but to do the artificial ones, I have to change the position of the pick to between my thumb and middle finger and hit the harmonic with my right index finger. The way I hold the pick (which is the only comfortable way for me) doesn't allow me to do them with my thumb. That's ok, though, because my index finger has better accuracy anyway. I tried for a couple weeks to do it with the edge of my thumb, but it never happened and I just gave up. Then I saw Eric Johnson use his index finger, and that was the ticket for me.
