There are an assortment of crafting threads, an old knitting/crochet one that didn't gain much traction, a fiber arts cow thread in BP, and the most active is the show and tell craft thread in Gorl Tawk. None are routinely updated and I think that is partly because the individual interest in each textile hobby wouldn't gain enough activity to support a thread longterm. I agree that having a Textile Arts General would probably be the best move, just to generate routine discussion. Usually people have more than one fiber related hobby anyways so it wouldn't be too weird I think? I guess if home renovations are good to talk about here, then so should craft projects?
Also, even embroidery is practical! It's used semiroutinely in quilting, which is another hobby that I think can be included here. I repaired a tshirt the other day and embroidered something over my repair to make it look intentional. Textile arts in general is pretty self-sufficient, the choice to either repair what you have already or make something high quality so you won't have to pay for garabge clothes is all part of breaking the cycle.
