Side note: Because of the contest I have set this design's fabric mode to a 4.21 X 9.84 scale. All other modes are in approximately 1.72 X 4. Though you may, of course, choose any size for this design, I plan to re-set it to 1.72 when the contest is over. If you would like another size, just ask before ordering.
