I was asked how to display the CD calendar, so I thought I would offer one way that I know to display them. I am sure there are others. I take an empty CD jewel case and remove the top from the bottom pieces. Flip the top piece over and reattach to the bottom so that it basically folds over the other way. It will not go shut, but instead form an "L". The calendar then slides in. The jewel cases I use (I assume they are standard size) takes a 4 3/4 x 4 3/4 inch paper.

Hope this makes sense.
