YouTube historical costuming/sewing has Bernadette Banner, Rachel Maksy, and Morgan Donner. Rachel Maksy is more on the cosplay side, with some wildly creative stuff like making dresses out of bubble wrap or potato sacks.
I think everyone I'm posting applies to the question.
All channels I've followed for a couple years at least, decent seeming people putting out cool, informative videos.
I can't think of specific accounts but I see a lot of fun stuff on my tiktok fyp. I see a lot of stain glass makers and rug tufting atm. There is one person making foam cosplay armour and I'm so tempted to give that a go.
