Well, the Spring one was our first but I didn't do anything Spring-y. I just got a bunch of cute stuff...Woops!
I will probably do the same with this one, though...I agree with you guys that it'd be different if it was a holiday thing like Christmas or Valentine's or w/e.
I also agree that Halloween would be such a fun theme! I was thinking about this, actually. I'm going to look for a cute/fun costume & add that in if I find one.
