It's Day One of 2002 and people are saying, "out with the old and in with the new." If your resolution is a wallpaper makeover, join the revolution. You're not the only one making a big paper changeover. Today 12 European countries switch from traditional francs, marks and lira to new "Euro" dollar bills and coins. The old currencies will be phased out in just 60 days. All paper changeovers -- whether a global currency switch or a wallpaper makeover at your house -- require a smooth plan for a successful result. Removing old wallpaper is just the beginning. After scoring, soaking and scraping, wash walls with an industrial cleaner like TSP (tri-sodium phosphate), patch and sand dents and gouges, and repair all imperfections. Everything you ignore shows up in a big way once it's papered over. Changing paper? It's no big thing if properly done. And that's the On The House tip for today.
