I have tried to befriend one but failed. One spell that worm for me is this; The Fairy Call
A Spell for Summoning the Fairies
Sit where the cat sits. Cross your toes.
Close your eyes. And smell a rose.
Then say under your breath:
"I believe in fairies, sure as death."
Gutterpuss and Cass!
Come to me fairily
Each lad and lass!

I know this worked because I can sense them after this. Haven't befriend one but still remember, try to bring an apple or a rose.
