I read all you could know about book binding fanfiction, never done it.
Found it hard to parse, and my mind immediately went with “Yeah, of course people have written fanfics about book binding,” foolishly extending rule 34 to cover it. Of course, there might have been that one fanfic about bookbinding.
But yeah, of course people have printed and bookbinded (bookbound[ed]?) fanfics. But for that to have a community? That’s unexpected.
