I have been making my own journals for years at this point.

Great jig in this video

This video, while not mine, is a nice overview.

Each word backed by a stitch

I use a utility knife on a cutting board, but I guess that roller knives would work well.

This is also not mine, but is a helpful tutorial

And some nice helpful instructions thank to booklyn.org

This journal was in use for about a year, in and out of a backpack. My cover sheet wears.

I have tried using this paper with mulberry leaf as both a cover and end paper. It has held up well. The last signature in the journal I printed for reference, while in school.
