Now what I don't know for certain is whether that grey line is going to print. See, they say to leave that distance between the inner graphic zone, and the outer 'bleed' edge empty in order to achieve a white border. Which would make sense if you could choose the color of the mug, but the only choice appears to be white... so, I'm not sure if the gray border will print -- I'm going to remove it for the final artwork.
Here are some more:



Ideas and observations are welcome. Also keep in mind that these are actual size -- the outermost oval is 2.91" x 4.58", and 'wraps' a bit around the mug.
EDIT: These are to scale, but larger than the actual size, LOL! (That's a monstrous cup.)
