Thank goodness these are up! We cleared some much needed space on the desk and the boys have ALREADY been more drawn to the books! I put up the first shelf and added books to it to see how it was working and as I was putting up the second shelf, Rookie kept interrupting me asking for books to read. The only negative is that the type of shelves they are will not hold up to weight, so an unauthorized tug on the bottom shelf yesterday left me drilling new holes and rehanging that shelf. Hopefully, we can keep from that in the future.
