Kind of related:
In Bradford more than a century ago, it was realised that children destined to go into service but who had -6 vision would probably not be affording spectacles throughout their lives, so would be effectively blind.
Instead of funding sight tests and glasses, they were instead enrolled parallel in the school for the blind and were taught closework embroidery and other skilled crafts that require close vision and concentration, with the idea that throughout their lives they would have an income.
I can't decide if this attitude is more frightening or enlightened.
I'm a lefty in a lot of my crafting, but decided that the way to stay healthy was to do nalbinding righthanded. My right side was a bit wonky already and needed no more rsi invoking actions. Spinning with a spindle helps me to loosen up my shoulders, especially when I'm plying. The bigger the movements the better.
I once knew a organ player who would slouch between numbers but sit up strait as soon as he started to play.
I have a terrible time with caluses. I tend to switch between textile crafts, so it seems as soon as I've grown a sewing callus I start knitting, then as soon as the knitting callus develops I start something else... XD
All three of the worst injuries I've were with sewing. As follows:
1) Was pushing a needle through multiple layers of dense fabric and the eye end slipped and went under my thumb nail. It then went septic and I ended up with a little abscess under the nail. Luckily I did not lose the nail.
2) Snapping synthetic thread instead of cutting it. I was doing a hand-sewn dress and eventually it cut the side of my hand, right on the little finger joint. Very annoying as it took ages to heal as it was on the joint.
3) Cutting thread and overshot with the scissors and cut the between-joint part of the underside of my finger, on the hand that was holding the thread taught. Went suprisingly deep.
Being a hand-tools only kinda person, even though those are my worst injuries, they're hardly major ones.
