step three is to put a bunch of white glue along the (bound) page edges, then put a fabric strip on top of that, then add more glue, and then finally add a paper strip cover to make it look a little nicer. there's a special paper made just for that, but i don't have any.
@tubetime Wow, flashback to working in the bindery at the local college library while I was in school. We'd bind a year's-worth of a periodical into a volume to go in the archives. There was a special bookbinders vice to hold the stack, then drill through in several locations, sew, glue with something called "runny paste", a strip of mesh, more glue, double-stitch binding to hold the cover boards than colored binders tape to finish it off. I did many hundreds.
