Make a small sketchbook from one folded signature and a single thread. Four letter-size sheets create sixteen page sides; a folded cardstock cover protects the pages and extends slightly past their edges.
Use paper that folds cleanly and a cover that can bend without cracking. The three sewing holes sit on the center crease, so check the alignment before piercing the stack.
The sewing sequence follows the Library of Congress pamphlet-stitch handout.
Questions
How many pages does the sketchbook have?
Four folded sheets create sixteen page sides before you add the cover.
Can I use ordinary sewing thread?
Use a thread that passes through the holes without cutting the paper. If it is too thin or slippery, test another thread on a folded scrap.
What if the paper tears at a sewing hole?
Move the top and bottom holes farther from the edges on the next copy, and pierce the stack with the awl perpendicular to the fold.
