2. Throws are easy, inexpensive, and perfect for a quick update and to add functional warmth. West Elm has some fabulously chunky ones that are also great to give as gifts. While I like wool best, for feel, comfort and durability, acrylic throws are very nice and often under $25.
3. With new flame-less candles, you can create instant ambience anywhere, safely. Many have 5-6 hour timers that you flip on once, and they turn on and off for months until the batteries are depleted. I found some with remote control at Kohl's! My Sanyo batteries are rechargeable too!
4. Add drapery panels to your windows. The fastest way to frame a view, add texture and warmth, is with fabric. Of course you can have blinds and panels! You'll get awesome function with your blinds, and a wonderful aesthetic with fabric drapes. Can't do that much? Consider a top treatment only, to dress up and conceal blind hardware.
5. Dress up your entry. Add a wreath - real or faux- put down a throw rug, add a narrow shelf or table and put a small lamp on top. Hang a mirror to capture all of the light from the lamp.
