How do you keep from getting wall paint on the ceiling, or get a nice crisp edge where there's a transition? I tried the blue painter's tape, but some of my new paint came with it when I pealed it off. After 3 days, I thought the paint would be dry. Despite my best efforts, I seem to get paint on the ceiling, and not get a crips edge at the ceiling/wall corner. One of these days I have to go back and do touch up where some of my wall paint pealed off with the blue tape. After I finish my taxes, after I quilt my neice's baby quilt (she's 6 mo).
