Tree book shelves -- great for kids room. Enticement to read. I'd like to see it made with darker wood or painted a rich brown color and placed in a living room. Also, this is full like a summer tree, I'd keep it more like late autumn with fewer displays.
Reading corner - I love the wooden letters (from JoAnn's painted white) the framed book covers. IKEA spice racks painted white for the bookshelves and dot rugs from IKEA. I would love to do this in a corner of our family room!
