Bookshelf for Allie & C's toy room

I love coming up with projects for our house and most of the time my husband thinks I'm crazy helps me to make my ideas come to life.  In our new house, the basement has been made into Allie and "C's" toy room and I've been trying to come up with some creative and inexpensive ways to make it look homey yet organized.  I'm so excited that my "bookshelves" worked!  We used vinyl rain gutters and spent less than $10!  I now want them in not only both of the girls' rooms, but also my classroom!!!
