The tree bookshelf from designartist is probably nothing new to the interior design buffs, but I just got my first look at it, through Martha Stewart's Living magazine.
While this one still looks a bit too kid's room to me, I would do it in all white, or silver or gold leaf.
Or just have a part of the brunches like this one from Olivier Dolle.
And I would certainly stack up all my accessories on it, like hats, or maybe shoes if I place it lower. Wouldn't it be cool to have all your high heels purched up on the branches?! So here is a collage of what my tree branch shelves would like! As you can see bags and shoes do grow on trees!
