If you have a windowsill sitting bare at 3800 Main, you're missing a big design opportunity. Here are some ways to add style to that humdrum windowsill:

1. Display your new crystal collection. If you feel like the energy in your home is a little out of whack, crystals could help—if nothing else, they'll add some glitz to your windowsill.
2. Add a garden. Test your green thumb by putting some potted plants in the windowsill. Choose planters that match your existing design.
3. Transform it into a reading nook. If you have a particularly spacious windowsill, you can turn it into a reading nook with the addition of a few throw pillows, a stack of books, and anything else you need to get cozy.
4. Create ambience with candles. Lining up candles of differing heights not only cultivates a romantic atmosphere indoors, but also looks pretty cool from the street.
5. Stow stuff. If you're lacking enough storage space, make use of your empty windowsill by filling it with cute boxes and stowing any odds and ends there.
6. Use picture frames. You can never go wrong with adding some more photos of your family and friends to your apartment.
