Sorry...:-) you could do what Susan said and hang them separately...I think that would work pretty well. Incidentally, I bought the ones we used at my brother's at a Coast to Coast for about $3 each.
As for the film, this is where I got it in Casper: Builders Mart 665 S Walnut CASPER WY 82601-2312 (307) 234-3545. It comes on a large roll, like oilskin, and they cut off however much you want, then you cut it to size for each window.
You apply it by spraying the window with water from a spray bottle, then starting at the top, get your corners squared and it works best if you use a squeegee to smooth it down the window, in order to get all of the bubbles out, etc. It really was amazing how much heat and UV rays it blocked out. At the time, I wanted to put it on all of my car windows, but had no a/c, so it wouldn't have been practical.*bg*
Now that I've told you all of this, HERE is a good article, with piccies even(!) which explains it a lot better! Good luck!
