Separable elements can be copyrighted (such as a fancy cast figure on a belt buckle) as can original art. The big question is what constitutes art. Attribution has nothing to do with copyright and in fact can be a violation of trademark in and of itself (think of the brouhaha Alice Starmore raised with using her name to resell her yarns. In the US, quantity made has nothing to do with whether an item is violating copyright or not (highly unlikely). Fair use has nothing to do with attribution. The final object is not what is covered by copyright, but the written words are. Templates are specifically not covered. As Stanford University's Law site says:

In its most general sense, a fair use is any copying of copyrighted material done for a limited and “transformative” purpose, such as to comment upon, criticize, or parody a copyrighted work. Such uses can be done without permission from the copyright owner.
