We just had a nice, big closet built along one wall of our bedroom. The contractor curved the wall into the ceiling so it has a cove affect. (other walls have this but have a slight slant lower on the wall shows a difference between the wall and ceiling). How do I now paint the wall and not have it run into the ceiling? There's not line or corner or anything. Only have about 4 inches above the closet trim so not much room to add more molding, plus it would look odd as there is none on the ceiling in the rest of the room. I want the wall red and the ceilng a creamy white. Help! thank you!
