Alec and Scott,
"Since the spine is approx half width you just corner drag so the height is correct then drag the outside edge inwards to fit."

I have several CD/DVD Cover programs including Avery Products. I have no problem with the art work. No trouble with the standard 3/8" spine case. The case I now have is 1/4" spine that is open in the rear so you cannot use the regular fold up edge insert. Maybe there are 1/4" case's that are made like the standard. I will have to check the stores.

Thanks for your replies.
