A few months ago I found this tutorial on making bookshelves out of rain gutters. It took me a while to get up the motivation, but I did. The workload was tiny and the result is fantastic! The bookshelves don't take up much room at all and all the books are facing Lorelai, which someone once told me was supposed to keep her more interested in them. We'll see how that works out.
Lorelai loves them. I might even have to throw a few up in Emerson's room!
