Does anytime know any weaving lessons in the Northern Virginia/Washington DC area?

I've done a bunch of searches, found a guild, and yet I can't find any lessons. I searched yarn stores for classes but everything's knitting or crochet, nothing is for weaving.

I just spent a week warping my Peacock table loom using countless YouTube videos, only to find out I made a stupid beginner mistake and need to cut everything off and start again and I'm extremely frustrated. I appreciate any help people can offer.
