On the topic of the hole....
What if the seam is on the button side? Then the hole could be made by the end user with a simple hole puncher (and no need for a deep "throat" to the punch), half on each end of the vinyl. This would also allow for easier application as the hole could be cut before applying and would facilitate lining the hole up with the button. Also, any differences with button location could be easily adjusted for.
The other benefit of a seamed button side is that when the LPV is laid down on a table the button tends to roll to the unit until the button side is "down" (at least mine always does?). Any slight "offness" of the seam would be less visibile as it's more-or-less facing the table surface. Did I describe that right?
