Hi I am a relatively new painter. Therefore I am often looking for ways to improve. The room I am about to paint currently has a mist coat. The ceiling will remain white and the walls will have a colour. I often find it tricky working out where the ceiling starts and the wall ends. Is one way to get around this to put frog tape on the edge of the ceiling? This should ensure you avoid getting colour on your ceiling and you get a sharp cut in line. Any other tips would be appreciated. I have found the Idadho painter on YouTube to be a useful source.
