Easy as one, two, three...
I looked on craigslist for four shutters and paid $20 for these. I washed them down and spray painted them the colors that I wanted in my spare bedroom. It really is THAT easy!
This room is not finished. I plan to get or paint old night stands white. Place a nice country themed lamp on them and also add more pillows. I originally wanted a yellow quilt with a little green in it but this quilt will have to do for now. :) Here is the original picture that I got the idea from. It would be cuter if the headboards were wooden so that you could make them more rustic looking.
