Do you have any decent local bookstores nearby? You might be surprised at the variety of magazines they have once you skim past the usual options. I've seen all sorts of niche publications, including zines. Most are not for me, but that isn't a problem since there is usually something that catches my eye.

You might find something that grabs you from the list of exhibitors here: https://www.seattleartbookfair.org/Exhibitors Or look for similar events and check out who attends.

I like reading about food, so places like Omnivore books have specialty books or magazines that are not just recipe books. Though I do like cookbooks. https://omnivorebooks.myshopify.com/
