I passed your questions along, and received this in response. (Some names have been removed.)
"I had to smile at the first question: where do you feel the burn? the most common ailment that I am aware of in production weavers, or those lucky ones who can weave more than 20 minutes a day, is "weaver's bottom" check out the medical terminology here

Ischial bursitis, I guess, not unlike what your butt feels like the first time you ride a bike or a horse after a long absence. A production weaver friend of mine has an adjustable bench that she can vary the tilt on, with a sheepskin for padding and she always has several looms going at once so she can move from one to another to avoid the problem. Weaving in general is not hard to learn and probably every household, at least in the country, who may have been more self-sufficient had a loom around, even if just a "barn loom" home-made of rough wood and with string heddles. **** **** (1834-1921) is said to have woven her own fabric for clothing, in a family history; don't know if ***** did, cloth was probably getting cheaper by then.
Jacquard looms, however, were and still are, a specialized loom as your writer indicates, and I don't know of anyone here in Utah who has one, or if they are still made for personal or household use. I imagine that folks still use them, but the weaver would definitely be more interested in more historic or authentic techniques and they are out there. There is a picture on this link:

More people who are doing more complex weaving these days, use what are called "dobby" looms, computer-controlled, which I find a rather humerous combination: computers and looms-whatever.
Most folks who are interested in weaving authentic historic coverlets without a specialized loom, and there are a lot of them, use a technique called overshot, where the base fabric is woven with a naturally colored finer linen or cotten thread and a pattern weave is done with a thicker, colored, usually wool yarn. The resulting coverlet reminds me of Colonial decor and there are a lot of collectors out there.
The writer's use of the term "woollen" made me cringe though. "Woollens" makes me think of wool long underwear. I think that the generic collective term for all household fabrics: coverlets, sheets, tablecloths, napkins, etc. would be "linens". Just my opinion, and more than you asked for. I hope that this helps."
