Besides the upstairs, the most important room for us to have ready was the guest room. (It is one of the two bedrooms on the first floor.) In this room, we tackled the less-than-stellar walls with a TON of scraping and skim-coating. Afterwards, Brent said...never again-new drywall would have been easier!
This is the "girliest" room in the house, but I like to think the aqua and green color scheme keep the men who stay in it happy.
