I have a problem with people that say things like "Garth got dropped on his head when he was a baby" -- Dude was a frigging dentist (do you have any idea how hard dental school is?) before he became a hunter. And when the man who was a support and resource for the entire hunter community died and the two most notorious hunters in the US disappeared, Garth stepped up and kept the hunter world spinning. Just 'cause he's cheerful doesn't mean he's stupid.
Here's the real trick for perfectly crisp lines: seal the edges of the painters tape with some of the base wall color before painting on the contrasting color. Don't paint the whole width of the tape. Just a bit along the edge of the tape on the side where the stripe will be painted. Let that paint dry and then paint your stripe color. great idea!
