Yes Jerry, but in the chaos is beauty

One thing I noticed on both mine and Guy's original seats is if you look at the seam at the top center of the headrest, and look at the top row of "squares". Using the seam as a centerline, to the left, there are 6 squares, from white to black, and to the right, there are 8, again from white to black. Both seats are identical, and Guy's are too. The Classic 9 seats show 6 and 6 squares from the center line. In fact, it looks like like the seats between Guy's originals and mine are the same in all respects. If that's true, then how can the be screwed up? How can the pattern be repeatable?

I kind of agree, Ed. Beauty in in the eyes of the beholder! In this case, however, I find that even as screwed up as the Factory Pasha pattern is it still tends to convey some of the dual appearance of a true Pasha pattern.

Your problem is that your pattern is screw up, but not enough to completely eliminate the magic of the pattern. I suggest that when you count 6 columns in your head rests on one side of the center line and 8 on the other that that ought to be telling you something about the pattern. One thing it should tell you is that the overall pattern in your seats is off center. It is off center about as much as the drivers seat in the Geneva show car that Ferry Porsche is sitting on, but not as much as the passenger seat in that car. On the other hand, The corners of your seat back head rest pattern is just what the pattern dictates, and that is that the ends of each row crossways should end in the opposite color. Yours does that almost exactly; but your pattern is still screwed up.

Your Pasha pattern is almost completely missing the rational consistent row and column reduction ratio or factor. That is also because the pattern is screwed up. However, I notice that very many of you, on this forum, are unable to see what I have been talking about. I think an old saying kind of comes into play here, but in the reverse. That is that "I think you cannot see the trees for the forest." So, I am about ready to throw in the towel. If I ever do anything with the pasha pattern it will be for my own use.

Toss . . . fluff . . . . plop!!!

Is it? I'm not sure.

First off, does anyone know what the factory pattern layout was?
What was it supposed to look like?
Centered? Symmetrical? Edge symmetry?

I have no clue, but Ed's seats are a bit telling.

The 'center' of the pattern is not centered on the headrest.

Nor on the rest of the seat.

It looks more like they were going for 'edge symmetry', where the pattern on the borders from cloth to leather (vinyl) matches (or mirrors) on both sides.
It's not absolutely perfect going down the seat back, but it's pretty close, and it looks like that area is where the 'close' was what they wanted.

Jerry is right. the original pattern is very....odd. see the red rectangles in eds headrest.

As far as where the pattern was placed the system was not exactly precise, however there must have been some sort of guideline/ rejection point for positioning.

Yes Joe, that's my observation too, but that is not unique to my seats either. Guy's original seats appear to be the same in this regard, so that must have been what the factory standard was. And what's further interesting is that the default to right off center is the same on both the passenger and driver seat. They could have made them mirror each other, but they did not. Guy's new seats attempt to align the pasha in the center from the headrest down. Again, it takes a pretty discerning eye to tell the difference, other than a general feeling of, hmm that does not look quite stock (plus the top most row in the headrest isn't straight on the horizontal plane, which throws it off a few rows down; that would drive me crazy more than the pattern being off somewhat).

Drooman, your pictures are interesting. I like the one with what appears to be three factory guys puzzling over the placement of some kind of patterning dies on the Pasha material. What doesn't show in the picture, but I can clearly see, is the big question mark in the air above each of their heads.

Your other picture with the red boxes drawn on it is not correct. The Pasha pattern requires that each row cross ways and each column up and down all end in opposite colors, black and white in this case it appears. To find the center of the pattern, and assuming that the small blocks are in the center of one pattern repeat, you simply follow the diagonal row of white blocks corner to corner that form a straight line one way and the black diagonal row the other way. Where they cross is the center of the pattern. The center is always made up of four blocks and their common corner is the center of the pattern. That means that the four outer corners of the pattern has two black squares and two white squares. That means the the blocks making up the two diagonal lines of blocks are, or should be, actual squares. That also means that each row and each column ends in the pattern repeat in opposite colors.

Your red rectangles need to be extended to the right by one column and down by one more row. When you do that you will see that the pattern is just not a bit "odd." but in in fact pretty screwed up.

I also notice, and it is kind of cool, that the two workers both got the memo about the dress code for the Pasha day in the upholstery Shed.

Remember, the genesis of this pattern is from the art history time period known as Op Art... not Op Science. Our science minds may not be able to fully understand it (as much as we may try) or apply math in order to make sense of the pattern.
As difficult as this may be for us to grasp, Imagine the challenge of that assignment within the pure science halls of Porsche. In droomans photo of the cutting room, I imagine the gent with the hat was an outside art consultant brought in to direct and council the cutters;-)

Again, the definition of 'screwed up' is highly dependent on what the definiton of 'correct' is.

Without a definitive answer on what Porsche was trying to line up, without knowing what their criteria for 'correct' is, it's hard to know.

I don't see Ed's seats as 'screwed up'.

The pattern is pretty well 'edge symmetrical', although the black/white squares are mirror.
If that was the goal, then they got it right.

If that wasn't the goal, then they didn't.
