Adjustable Curtain

Our TV room upstairs is on the southwest corner of the house and has no shade. So it gets really hot in the sunny afternoons. So I made a curtain to keep out some of the hot sun. Since we're renting I couldn't fasten the curtain permanently to the wall, so I used 3M hooks. I bought some upholstery fabric and backed it with muslin. I sewed twill tape hooks along the top and bottom edges of the curtain and then sewed buttons along the middle of the back. So I can hook it up in half like this or button it only part way up or leave it all the way down.
