How to hang pictures around an attic window. The key is start with a center piece of art then work your way down the wall with various picture frames, sizes & shapes. An adjustable picture hanger is a must to make this easy and fast.
Kitchen: I really like the shelves above the windows. Not sure if it would look as pretty if you don't have window casings which we don't. I do like the curtains as well, not necessarily the color but the style. I also like the plants behind the sink.
