How do you keep the painted line straight at the top of the wall next to the

Masking with tape doesn't work for me. Using a shield looked like crap.
Cutting in freehand with a brush is the best I can do and it still looks
bad.

Any tricks?

Because of the way the joints between the walls and ceilings are
finished (tape and spackle), there never is an absolutely sharp corner,
so there is usually a paint overlap at the joint, either on the wall or
ceiling. If it bothers you that much, bring the ceiling color down a
bit onto the walls and use a wallpaper border, or just install crown
moulding.
