You know how for natural harmonics you fret lightly touching the string above the 12th or 7th or 5th fret (the easiest three)? Well, it's the same principle as changing open chords into barre chords. You fret a note, say the 5th fret on the e string. Just go up 12 frets (or 7 or 5)to the 17th and lightly fret the note (as you would with your left hand on natural harmonics) with your right hand index finger and pick with the pick between your thumb and middle finger.
This produces a result just like as if you'd hit the 12th fret natural harmonic on the 5th string, incidentally creating another great way to tune your guitar. You can't trust comparing natural harmonics of the 12th fret on one string and the 7th fret on the next one up because you'll be a little sharper every string up, but if you tune by fretting the 5th fret and hitting a 17th fret artificial harmonic (or fret the 4th fret and do a 16th fret harmonic for the B string) compared to a 12th fret natural harmonic on the next string up your guitar you can hear differences between the strings better (especially if distorted), and the strings won't be as differently tuned as if you use natural harmonics.
