I live in an old trailer where all the walls and all the carpets are brown. The walls seems to have a gloss on them and they're the "wood pattern" kind. I've been thinking of trying to paint over the panels since I've seen a house where this was done successfully. Does anyone have any tips on how to do this? What colors could I go for to brighten up the rooms and make the trailer seem bigger? I can't afford to do anything about the ugly carpets but I figure the walls would make a world of a difference.
