I've just got this question
Quote
I just saw your critique post with the nails with painted swirls. Would
you mind telling me exactly what brush you use for for this kind of
detailing as I am trying to learn artwork but am struggling with
finding the right brush.
This could be good start for a new thread 
I use only sable brushes- Kolinsky or Squirrel for my nail art.
If I'm trying to achieve tiny details/ lines I use my Kolinsky brush No 0/10 undefined
For bigger details like petals leaves...whatever..unless it big enough I use my Kolinsky brush No 00 
o'k...need to run now...will continue later.
