Well, you can say you're trying not to be a d**k, but it seems as though you are...
I look at mine, and I don't see that many wrinkles or "stretch" areas, while I look at yours and see the same things... The only difference I see, is yours is a lot more contoured, which you stated, but that may be what you wanted. I'm VERY happy with the way mine is turning out. If it's not your style, it's not your style. The stitching is done the way I wanted it done, I didn't want a french stitch on every seam. If you look, I didn't use red stitching for the whole thing. Again, how I wanted to do it.
6 hours was with the middle, and one side already cut as it was the same as the passenger side. And one of the guys that I got advise from here, that does upholstery on the side, quoted me 8 hours for the entire rear seat, him doing it himself... So, maybe some shops are slower, and some are faster... Don't know what to tell ya.
Either way, I'm happy with it. VERY happy with it. So, you don't have to convince me that yours is better than mine. It's ok that you like yours that much, as I like mine.
Thanks for the words.
