That kind of detail obsession has its place in a museum/professional reenactment setting, but on a hobby level it strikes me as fanboy (and it's usually men who get wound up about such things, not women) obsessiveness on a level with arguing over whether Sgt. Rock could beat Captain Picard in a fistfight. Stitch-counting really doesn't teach one anything particularly meaningful about the reality of the Era, so -- meh. People can do it if they want, but don't expect me to care two cents that I have plastic tips on my shoelaces when only aluminum would be correct for the second quarter of 1935 . I'm not "reenacting" anything, I'm living my life.
Absolutely! I'm not posing for anyone else and have no interest in being part of a sub-culture. I just want to live life the way I like it.
