I want to add some additional options to my photography listings, but I don't know if I should add them as add-on options (creating a whole new listing) or just add those options to the drop down menu in the current listing. Those options being, canvas, mating, and framing.
This also leads me to wonder about sizing options. Currently I have all my sizes in one listing, three options total. Should I create three listings for one picture, offering a single (and different) size option per listing? Or should I just keep that part the same?
