For sewing there seem to be two trying to get off the ground but neither seem super active. I’ll probably just pick one at random and start posting in it if that doesn’t change but they’re !sewing (direct link) and !sewing (direct link)
!leathercraft (direct link) isn’t something I do personally but I do enjoy perving over their projects anyway.
Erm…if I find any more I’ll come back and update this lol. Kind of one a one-woman mission to build a good list, then hopefully convince the various mods to sticky it so people who find one of these places can then find all the others too.
(Also p.s. I don’t know how to format these links for Kbin so sorry if they don’t work. But hopefully I’ve made it a bit easier for any other Lemmings who stumble across this comment.)
