curtains on walls.

[thirteen]

I'm thinking of covering up my light colored walls with curtains. Looking for advice from anyone who has experience with this.

There are many ways to do this, but I'm not sure what works best for the lowest cost. Should I buy blackout curtains, or use fabric and hang them somehow. I don't know anything about sewing. What about curtain tracks that hang from the ceiling? Or can I just use curtain rods and still get a seamless look, like one continuous curtain?

I would love to see pictures and get some advice from anyone who has a room like this.
