@ancients I asked the artist who wove the rug to see if the backward pattern was intentional. From her perspective, a Navajo rug doesn't have a front or back, and she didn't realize that it made a difference from a hardware perspective. She didn't think it made sense to contact the museum since it was near the end of the exhibition. But maybe I should contact the next museum.
@kenshirriff @ancients please don't spoiler, rather log where it was "right and where it was wrong-sided". Each year at the Christmas market sets up this kind of abomination (inspired by artisanal pyramids driven by the rising gas from candles) and I'm always curious if they attach the electricity right or not, resulting in correct or incorrect rotation.
