Apologies, I'm afraid my time is limited for much of anything outside of work. I essentially do these for myself now as there is little interest in them outside of a few edge cases. I appreciate your interest, and thanks for the kudos.
You can find more covers, and perhaps interest in your jewel case idea, within the GOG forums.
Sure, no problem, maybe I will try to create something from scratch by myself cause I rarely see jewel cases used this days. Anyway, thanks for your work as I was looking for some neat looking cd labels for my GOG games and yours are exactly what I was looking for.
