I follow another small project who had to stop shipping from the UK to the EU from Tindie, because Tindie wasn't handling the VAT requirements that brexit opened them up to.

I can't promise I'm up to date on that - that was two years ago, but they're still selling to the EU from their own site, and rest of world from Tindie. So I'm working to the assumption that they wouldn't still refuse EU sales from Tindie unless they felt they still needed to.
