Make Your Own Notebooks
For the really hands-on minded, DIYPlanner has this piece on making and binding your own books:
“Today, I‚Äôm going to show you how to fold the folios, make a single signature, awl punch the paper and then sew your book with a bookbinding needle and waxed thread. While I am giving instructions to create a digest (5.5‚Äù by 4.25‚Äù) sized book, you are welcome to cut your paper to make your book any size you want.”
