Ever since I read that the holes on the Paul Smith jumper were NOT random, I knew I wouldn't be fully satisfied until I figured out EXACTLY how the pattern worked. I have seen images made by others simply hinting at the existence of a repetition or only marking the location of every hole, but to my knowledge no image has attempted to FULLY BREAK DOWN the pattern to its basic indivisible unit and indicate how it repeats, and THAT is what I am aiming to do with this post, compiled after having stared at scores of photos of the jumper.
In each red rectangular grid is the basic cluster of holes. Since the jumper is supposedly meant to evoke the imagery of stars in a night sky, I decided to use constellation lines (here drawn in yellow) to try to figure out what this cluster may look like. A lion cub, perhaps?
On a size small jumper the cub's head/mane begins immediately below the collar (marked green), while on a medium the collar is a couple of inches higher up. The turquoise line represents the vertical central axis of the jumper's front.
For those attempting to make replicas, I would suggest starting first with the cub highlighted yellow before repeating downwards, planning the scale to make sure that the length of the jumper fit the height of roughly three cubs. Then, progress onto either side until you run out of jumper, taking note that each column exhibits a very slight upward shift in pattern from the one to its left.
Doing this has made me aware of how inaccurate my current replica is, and now I want to make a new one even more. I would be glad if this turns out to be of help to anyone making their own replicas as well, especially since @jarjar_ben, the maker of arguably THE BEST replicas out there, must be very busy taking so many commissions, and getting a genuine Paul Smith is sounding more impossible by the day. … And now I should stop procrastinating on my grad school apps.
