Depending on the style of your house, you may have a few dormer windows upstairs. I really love them as an interesting feature to the room and think highlighting them always is a great idea. Julie of Less-Than-Perfect Life of Bliss came up with a gorgeous and easy way to dress up a dormer window.
Julie created this little striped awning for her daughter's room and it really dresses up the area. The black and white stripes are perfect but any fabric of your choosing would look great. So how did you she do it? You'll have to go and read her instructions right here. I'll give you a hint - she used 2 tension rods.
