Hi I need some help trying to understand the subcategories. I understand how to set them up but what I would like to know is if I have two categories one for pearl pendants and one for pearl earrings and I make them both subcategories of Pearl Jewelllery what information goes on the Pearl Jewellery Page .. what purpose does the pearl jewellery page have?

Alternatively I could have a pearl necklace category and have a subcategory of it called pearl earrings and that would take care of the extra page .. is this the way most people split up their categories. Hope ive made myself clear here. Thanks for your time.
