What's in the Box? This is where I got my inspiration. She has lots of printables to share and she also has lots of other links to blogs and places you can go.
After reading that blog I joined a yahoo group for workboxes. There is so much info on there. If you decide to join be prepared for a high volume of posts. It's a very busy group but you will find just about every idea on there.
Those are the two links I will post. I'm sure you will find more by going to those two links.
