I’m legally obliged to shill the various crafting communities, my two most used are !knitting and !lemmy_stitch but you can find lots more in the sticky thread in either of those.
Then there’s also !imadethis which has been a bit quiet lately so if you’ve made something, go show it off!

Searching Lemmyverse is good for finding communities. !trendingcommunities is also a nice tool for finding new places....
