@futurebird a few years ago @mlemweb led an interview of authors of a python library for cross stitch patterns on the #fossandcrafts podcast

Perhaps they have a method for printing out the patterns like you want

Also, perhaps the #FreeSoftWear community has suggestions

I think there's a #HackAndCraft call going on right now

@xgebi I don't know of a marketplace, but I can recommend at least one indie designer and a couple other hopefully useful websites

the one indie designer I've bought (and actually sewn¹ :D ) more pattern from is scroop patterns / the dreamstress, who is not in the US (she's in NZ), and sells directly from her site
scrooppatterns.com/
of course that's just a handful of specific looks

There is another indie I've bought something from, Liz Haywood from AU, but she sells via etsy. :(

Then there is freesewing.org/ (free as in #freeSoftWear) that aren't traditional patterns, but made-to-measure ones and work in a bit of a different way. They have published freesewing.org/blog/us-and-eu/ on the topic of getting away from the US, and are here on the fediverse.

And lastly I follow a blog (the author is in the UK) that does reviews of free patterns: many are from the websites of indie designers (other from bigger sites) and may be a good source for additional sources of patterns.

¹ they aren't a lot because I enjoy drafting my own patterns
