It is best to fingerpick the strings with your fingernails as this gives a better sound. You should let the fingernails of your right hand grow to a length that is comfortable for your playing e.g., 1/16" (1 millimeter) clear of the fingertip. The thumb nail should be longer. Fingernails should be shaped using a nail file (emery board) so that they have a rounded edge and flow smoothly off the string after it has been picked.
