i have been working on neck these days.
sanded out head stock and neck itself with 120-180-240-320 grit.
After that, have started dealing with fret board before going to lacquer finish, decal on head stock and neck backside.
I prefer rounded edge a bit on fret board and headstock.
and fret bar edge as well.
now going to sand out fret board up to 400-800-100-1500 grit as well as fret bar with 1000.
