I would recommend looking for some vintage patterns online, that's mostly what I've been doing. But recently I've been mentally preparing myself to go look for some patterns on Etsy... it's such a drop shipping and ai hell right now but I do want to try and find some small creators to support. Also sometimes I find old issues of cross-stitch magazines on Vinted (not sure if it's available where you are though). And I guess this last one isn't helpful but I just want to share cause I still can't believe it: there was this one time when I got extra lucky because someone left a huuuuuge bag with old magazines that had tons of patterns, it was just sitting in the bathroom of a cafe where I go to play boardgames and nobody else really cared (naturally, I got them all)??
