"Fountains belong in the garden or on the patio."
Sight and sound of falling water is so soothing it should be part of your everyday life. Christy recommends you buy a small indoor fountain or make one by placing a pump in a favorite bowl or vase. Add water, a few plants, and plug in whenever and wherever you want, perhaps centered on an entry table or a side buffet. Or go for a more formal look by setting a fountain in a wall niche.
"Cushions, fine wood furniture, and porcelain pieces are strictly for the inside."
Flea-market furniture and attic finds are easily adapted to outdoor use, because if they fade, rust or peel a little, it's no big deal. As for cushions, Christy Ferer recommends you keep a big basket handy to bring them indoors overnight if it rains.
