Classroom Theme

Ok, I need some help bloggy friends. I am looking for a new theme for my classroom! For the last couple years I have done the ever-popular owls.

Super cute, right?? I only meant to keep it for a year, but I got pretty carried away buying things the first year. I had owl EVERYTHING... pencils, bulletin boards, calendars, you name it. After that, it just kind of spiraled out of control. My kids kind of assumed that I loved owls and started buying me things, so I had even more owls. Then, even more people assumed I loved owls, so they bought me owl things too. It got really out of control. I'm gonna confess something here... I have no strong feelings toward owls. To be honest, I'm just tired of looking at the same old stuff. It's time for a change! I've got serious mental block going on though. So, here's where I ask for your help. What is your theme? How do you incorporate it into your classroom? What sorts of things do you include in your theme?  Let me know in the comments!
