How would you get a good start on finger picking? do you use the finger nail?
I have never done it before. I have always used a pick.

ever played nothing else matters. Great for beginners, well the opening bit all it is is:

Most ppl use the thumb for the bottom two strings (E,A) then their index finger (D) middle (G), ring (B) and pinkie (e). As for which part of the finger it depends on wat sound you want. I usually jus ues the tip of mine n that works fine.
For more practice just pick open chords ie c, g etc....
Hope it helped.
