Thanks to teacherken and TheGreatLeapForward, I visited Amazon's user review pages for Avery Binders, and the Idea hit!
Today, I spent $2 at the dollar store for foam board, and $3 at the local hardware store for large snap-open key rings. A little glue and construction paper, plus basic black clothing--and I'll be Woman in a Binder!
May I recommend the idea to others? It's a great way to spread the meme!
