A few songs i intend learning to play use fingerpicking techniques & as ive never really seen a close up of a guitarist using his finger picking, id like to know if you play with the tips of your fingers(your skin) or finger nails, because i dont have long nails & i have fairly short nails & dont intend to grow them

if so is there any way to get around the "nail growing", ive seen some sort of pick you attatch to your thumb can you also get these for your fingers or what?

i really dont have a clue about this subject, can somebody shed any light?
