Maybe I’m not getting something here—from a business standpoint, why bother with the decorated ones at all? It sounds like you’re losing money on them, when you could just as easily be spending that time making 6 to 10 of the other variety—which you’ve said you have no trouble selling. Is your profit on the decorated ones 6 to 10 times as much? If not, why waste your time?
If it’s just because you really, really enjoy making them … then make them on the weekends, as a hobby.
