I will never again do fake nails that don't have those tabs on the end to help you put them on.
I have just glued every combination of finger to toe to nail to finger possible.
At least my toes look decent now.
(Seriously though - I picked up the guitar the other night and my fingertips HURT from practicing chords. It's been years since I started trying to learn it. I'm actually considering just putting some nail glue on the tips of my fingers while I learn until I build up callouses)
