Some bedrooms catch a lot of sleep-disturbing light at night, but many sleepers like to wake up with a bit of natural light. Meet the morning halfway with a hotel-style setup of curtains over sheers, as suggested by Apartment Therapy.
The home and design blog isn't talking about the magnetic-latched, absolute blackout curtains you'll find at some motels with too much light. Instead, find a pair of heavy drapes that match your decor, and run them over some gauzy, privacy-providing sheers you can pick up fairly cheap at your local general merchandise store. As Apartment Therapy suggests, this setup blocks the majority of street lights, passing headlights, and other sleep-disturbing lights at night, but gradually lets in an adjustable amount of light each morning to help you wake up.
You could also combine this treatment with another measure, like the DIY window frosting Jason showed us. If you've found the beautiful mid-point between sound sleep and natural light mornings, tell us your own solution in the comments.
