My front window faces West. I have no tree in the front yard to provide any shade at all, so all the sun for the entire day comes through the front window into my tiny, airconditionless, poorly ventilated house. I bought a really cute bamboo blind for the window and, after installing it, realized it was as useless as hanging up a piece of Kleenex.
Rather than taking it down and getting a new one, I found a table cloth in a similar colour and threw it up over the shade. It worked a little better, but wasn't the optimal solution. I threatened to put tinfoil up in the windows -- both to keep out the sun and to keep aliens from reading my thoughts -- but Ky said it was too low class. Even for us. I pouted, but agreed.
Suddenly, I had a thought. (It scared me and it kind of hurt.) I would take the emergency tin foil blanket and put it on the window. But, I didn't want to appear low class, so I decided to do something else. I laid the table cloth on the floor, spread the foil blanket over it and tacked it in place. Then, I hung it up over the shade so the foil was hidden entirely between the table cloth and the shade. Works like a charm and no one will think I live in a trailer park.
I mean, except for when I stand on the porch with a baby on one hip, a cigarette hanging from my mouth, curlers in my hair, and a beer in my hand, screaming at the top of my lungs.
