The problem with hands, is that I keep ending up with a Moebius strip despite my best efforts.
(this is not technically a Moebius strip, it’s just the same feeling I get when you’re tracing one; for the Home Edders, Moebius strips are a fun activity, get the kids to cut out a strip of paper, half-twist one end, tape the ends together and tell them to draw a line on either the inside or the outside but not both)
