leather bound books?
how about being able to add images to the leather goods you create? Something that would be added to the objects description, such as "This is a leather shield, on it is an engraved image of a ruqua tree."
The artisan could be able to select from a list of pre-approved settings appropriate images to add, to avoid things like, "This is a leather shield, on it is an engraved image of LAANX SUX LOLOL!!!111!", the higher the skill the more images or more elaborate intricate the images can be. Lower skills you can add basic shapes or simple designs and work your way up. And, since glyphs are just images through which cosmic energies are channeled, if you have a high level in a Way coupled with a high level in the craft skill, you can add glyphs to the object, imbuing it with that spell.
