with a little mugger guy coming out of the side holding the spoon... you know its the"mugstir" so the mugster guy with a little bandit mask thingy can be looking like...don't steal my spoon....
this is all drawn onto the mug or painted or however they do mugs....lol
so under where you have attached the spoon you would see the decal ....
you could make male and female one's for your target customers i would make them nice looking funny muggers though..
i also think on the back of the mug there should be a small open spot like a speaking bubble where someone could write their name with permanant marker...maybe you could include a small clear laminate sticker and tell them to apply over name after writting... i am sure the cost of that would be fairly cheap and would make it nice and giftable....
