I have large windows all over my house and I live on a busy Street. I just moved here. I realized today that I can see inside my house at night even when the blinds are tightly shut. I tried turning them the other way and it made it worse. So I'm thinking about getting curtains.

My two main concerns are 1) I get claustrophobic and basically leave the blinds totally open during the day for openness and light but, 2) I like to walk around without my clothes at night... so extra privacy is needed.

Would sheer curtains even help? Is there something between sheer and blackout? How do you handle privacy in your home?

Also I heard somewhere that putting lights right by your window for backlighting can help. Could someone show me an example of this?
