I was looking for Mylar and the Blanket idea too... BUT

The best of all is this. The Dollar Store for Mylar Wrapping Paper!! I picked up 6' x 30 something inches for a buck!. Spent 12 dollars to cover every inch of my room. That and a staple gun....done!

Check out your local dollar store first, with Christmas coming, they usually stock up on Mylar for wrapping. Make sure you get the metallic, and not the clear... they look the same, damhik. :thumbsup:

With the wrapping paper, you get a nice even coverage, and it's much simpler to apply than the blanket that's all crumpled up. 4 staples on the top, let her roll down, and a few more on the sides. Done!
