Why is the stitching on blue jeans orange or gold?
My grandfather once told me, that for a brief period of time there used to also be a rivet on the southernmost part of the crotch of the jeans. Right where the two inseams of either leg meet. Wandering frontiersman, cowboys and mountain men found out quickly that squatting or kneeling down in front of a camp fire heated up that rivet amazingly quickly. The cursing and dancing that ensued afterward was apparently not amusing enough for Levi Strauss to leave it in… One of the benefits of being raised by old people, I guess.
