those r so cool!
Anything that looks like it was made on college-ruled/lined paper was probably made by me. Online, I'd say if you have Instagram, there are a lot of activist/anarchists groups that share materials there (as unfortunate as it is that Insta is the middleman).
Crimethinc has a lot of online zines, some of which are printed there. The creator of Electric Zine maker has a collection of zines on Itch which you probably have come across. Also, ol' reliable -
theanarchistlibrary.orgAs well as the
Queer Zine Archive Project, or the
DC Punk Zine Archives.
Hope that helps
