I do some moreso out of utility than as an art. I get pdfs of stuff I'm interested in that would otherwise be hard to find as an actual book (mostly /x/ shit) and make them into these softcovers with a flap. The design I stick with is based on this youtube video: https://www.youtube.com/watch?v=gJY4SJipiIo (there's actually three, this is the first one in the series.) Simple, cheap, and functional, just the way I like it. Bonus is you can use the flap as a bookmark.

Depends what you want to do. You can go crazy with expensive materials and tools if you really want to. But just getting started all you really need is paper, thread, a needle and a sharp knife. Of course there are more specialized tools that make things easier, but the bare essentials are pretty cheap as far as hobbies go.
