One of the first steps in making a space feel like home is hanging photos and art. You could do this with frames from the dollar store and mix in a decorative mirror or other matching, wall-hanging items. I want to do this with black frames and black and white photos, Playbills, etc.
I think the idea of book shelf stairs leading to a cozy loft is wonderful. I would love to make one of these.
Wall Decor Ideas - its in spanish but there are some great layouts for frames.
