Step 1: Gather Materials
The book I'll be showing you how to make here uses 5 sheets of 6 x 18 inch of white paper and a slightly larger sheet of corrugated cardboard, 6.5 x 18.5 inches. You can make your book any size by adjusting the size of the paper and cardboard, but following the same directions.
Tip: I collect sheets of corrugated cardboard from boxes I find at various businesses like grocery stores, furniture stores, and office supply stores. The best cardboard is 2-ply. I cut this cardboard up the size I need it using a mat knife or large paper cutter.
Step 2: Measure the Spine of Your Book
Step 3: Score the Spine
Step 4: Bend the Cardboard Until the Spine "Pops"
Step 5: Tear out the One-inch Section
Tip: Tearing this section out is easier if the corrugation in your cardboard runs longways, or perpendicular to the spine, rather than parallel to it.
