No, not that mug. These mugs.
Since I posted these on Twitter, I guess I should post them here.
Different photo merchandise sites use different dimensions. The Krait template was used with a site called www.vistaprint.co.uk The other two (Cobra & Vulture) were created for www.snapfish.co.uk / www.truprint.co.uk
So check the size ratio and use the right layout or your design will get truncated in a bad way. Download the bitmaps, upload the one you want to whatever local printing service there is and presto! Blueprint mug.
