John, I'm wondering what tuning you use. DADGAD is good for the artists you are emulating. Archie anyway. In fact you're setting the bar pretty high, Jansch is impossible and Archie is amazing (particularly in his seemingly effortless approach).

A lot of times you can do what you want by hammering on the bottom string with your left hand thumb--mostly 2nd, 4th, 5th frets. You need all five fingers.

Good luck
