It's very easy to make your child a theme binder using a variety of methods. I find you end up with a higher quality binder that's less expensive than some of the fancy ones you can buy.
- good binder that has a clear plastic slip cover -- whatever color you prefer. These can be purchased at Wallmart or your local office supply store.
- Color printer
- your choice of one of the color posters from the site
Short but sweet:
Print the poster.
Slip it in the front cover.
Change it when you get bored -- or for different holidays, seasons, etc.
