Step 5: Preparing to bind
Put little marks to indicate the top edge of your covers and five signatures.
Open your catalog or small phone directory in the middle. Open the cover or signature and place it so the middle crease lines up with the "valley" of the catalog. Place your template over the crease and be sure the top of it lines up with the top of your signature or cover.
Punch through the pre-punch holes with the awl or needle.
