I got a paint situation going on. We bought some new paint to paint the bathroom, seemed easy enough. After I masked everything off, removed towell racks etc, I start to paint. After a minute I realize two things. I cannot paint a straight line, I keep getting paint on the white ceiling. Secondly, I notice that the paint that is on the wall is showing through my new paint. The people we bought the house from did some dumbfangled sponge treatment to the walls. They put a 2nd color on with a sponge after they painted the wall white first. The part that they sponged on is bleeding through. How do I paint the trim as to not get paint on the ceiling, and what do I need to do about this other paint showing through? Any tips, or suggestions are greatly appreciated, cause then I can pretend that I figured it out by myself, and the boss (wife) will never know the diff.
