Since self-publishing and zines should be a big part of Unprofessional Press, I thought this would be a perfect match. (I just started with linocut prints, one step at the time.) A friend of mine is crowdfunding her own book called "Bücher binden" which teaches you how do create your own books. I already got myself the book plus bookbinding supplies from her crowdfunding campaign and invite you to do the same because I really want that she hits that damn goal!
Take a look at the campaign.
The book is written in German, but if you're interested in getting involved hit her up. She is also selling single instructions which are more like zines so maybe it is possible to get these translated.
