11oz/15oz black ceramic mug - Killdozer - this keeps me reasonable

I like black mugs and I cannot lie. The 11oz mugs cost $5.13 to make and $6.99 to ship, and the 15oz mugs cost $5.99 to make and $8.99 to ship, so my margin is ~$7. $5 of that goes to pay down my mortgage principal (not usury or taxes) and the rest pays for store expenses, designs, income taxes, etc. Of course, if you buy more than one of the same product type or supplier, I'll (probably) save money on shipping and my net revenue will be that much higher.  If you're poor or would rather not support me or want a different design or whatever, I want to make it easy for you to recreate this yourself.
