How can I format my image so it'll wrap all the way around a mug?
The maximum dimensions for an image on a mug (large or small) is 8.31" x 3". In pixels, that would be 1662 pixels wide by 600 pixels high.
If you make your image at least 1662 pixels wide, and no more than 600 pixels high, it will wrap all the way around the mug.
