This is a great little book for phone numbers and other random notes. You can make it any size you like, and the paper never had to go to the processing plant! Using a string binding instead of glue is easier on the environment, too. Some of the books I've made are for sale at my Etsy shop.
Recycled paper (blank on one side)
Thicker recycled material (postcards, envelopes, cardboard, etc.) for covers
Twine, yarn, or other string
Awl, drill, or drill press
Large sewing needle or bookbinding needle
Paper cutter, scissors, or utility knife
Step 1: Cut and Fold Your Paper
Step 2: Line Up, Clip, and Make Holes
Mark 3/8" from both to-be-bound corners (the folded side of the sheets). Divide the space along the binding between these marks into thirds, and mark those locations. These are where we make the holes for the twine binding.
Make holes all the way through the book with an awl, drill, or drill press. If using a drill or drill press, make sure to clamp your papers tightly down to avoid any paper ruffling. Placing a piece of wood under the book helps make a clean cut in the back.
