MMH - two sided display; no need to sheet rock some areas? -- tear out a section of wall between din/liv or kit/fam and build shelves into the studs, paint. Makes it more open, and useful at the same time!
Books, books and more books! I've always wanted to have a high-ceilinged room with books from floor to ceiling. so high in fact, that you need one of those slidey-ladders to reach the uppermost shelves.
Not sure what I think about using lighting in side the cabinets in the craft room. Maybe glass front cabinets on top of it? I tend to put small lamps into book shelves. So we are going to need outlets in the bookshelves. Any bookshelves in the house.
