Fran,
I guess we are on different wavelengths. I said the edges would be cut off because of the thin case having no index edge. Your template would not be a full fold for your front and back of a standard CD. Actually, I have not seen a template designed that way. What I was saying is that you would cut to the exact size of the thin case of the front of your design. Place it in the case and then design another one with added information if needed and cut to the same size and place it in back of the front design. I'm not talking about the BACK of the case, just inside, right next to the front cover. With the thin case, there is no way to have an index tab, as well as no way to put any info on the very back of the thin case. It will all have to be done in the front slot of the thin case. I hope this is understandable.
