I love that kitchen curtains don't have to be too fancy. When I'm in my kitchen, I want to be able to see out the window as I'm cooking, doing the dishes, or whatever. But, I also like a little privacy.
(This is the best before picture I have of this window.)
I was reading up on different window treatments when I discovered this idea and adapted it to my situation. I just bought some tension curtain rods and some cafe rod clips, though regular drapery clips would work, too. Then I took some cloth napkins that we got for our wedding (and never use) and clipped those on to the hooks to use as my curtains. We're going for a blue and white kitchen, so I think these work beautifully!
Other variations on this idea are using bandanas or tea towels. I think each window (I have two of them in the kitchen) cost about $6.00 each because I already had the cloth napkins.
