Bluegill Pattern Help

[Ge Khang]

Hey guys, ive recently started painting my own bluegills and was wondering how all you guys paint the black gill. Im using spray cans as well so its abit tricky working with something soo small. Ive been using just a sharpie but recently it has started bleeding like so.

If you have the patience, use blue painter's tape! Just use an Xacto knife or similar fine blade and cut through the tape to create the shape of the black "ear" portion of the bluegill. this should do the trick!
