I love this idea from Martha Stewart's Craft of the Day. It's a "button-up" window shade. What a great idea. The MSL instructions are not very detailed and the picture above is the only one provided (says me, who makes a mile-long post with a gazillion pics about my window treatment in my kitchen!), but it is a very simple shape so it should not be too hard to make. I would think you could do this to a panel you might already have, too.
