Still going to have paint line somewhere though?

One thing we always struggle with is getting a good clean line between
the white ceiling and coloured walls.

Paint ceiling first, and the top couple of inches of wall. Dia of
roller used to paint ceiling in reality, brush out the walls to give
and even surface, no gobs of paint from the roller end.

Walls, use a behind radiator roller to paint the top 4" or so of the
wall getting as close to the ceiling as you dare. This band of
painted wall enables bulk of the wall to be painted without having to
worry too much about getting close to the ceiling with a big roller.

I'm afraid that free hand with a synthetic bristle cutting in brush
is the only way to get a decent line. Needs to be fairly well loaded,
apply paint to wall just below where you want to line up to the
ceiling the use a horizontal but slowly heading towards the ceiling
movement of the brush to push the paint into a small "bow wave" and
edge into the corner. It's wall paint on the ceiling that really
stands out, a little white on the wall doesn't show as much.
