Years ago, we put all our movie DVDs into soft, black cases like these to cut back on shelf space. But over time, they got mixed up with the same kinds of cases filled with music CD's. I finally went through and reorganized our whole collection and labeled the cases using Joy letters and some strong clear glue. The "Educational" case consists of nature, historical and instructional DVD's. The other cases hold movies and TV shows. I also placed a piece of white tape on the front of each binder and wrote what was inside, depending how I alphabetized the discs. You can find your favorite style and color of Joy letters at your local craft store!
