those bookshelves in the school room

Two people have asked about those white bookshelves attached to the wall in my school room pictures down there...I meant to mention those! So cool! Those are rain gutters! haha! Like the super long pieces of vinyl rain gutter that you can buy at Home Depot? I bought a huge piece for something like $4, and they cut it into pieces for me at the store. My husband screwed them into the wall. Make sure you find studs, because they will hold quite a lot of weight with books in them. I love them! I wish I had more wall space to put in more! I got this idea from The Read-Aloud Handbook.
