What you'll need:
Cereal box or other cardboard for backing
Binder clips or rubber bands
Step 1: Cut your paper and backing
I chose to make mostly 5.5" x 8.5" and 5.5" x 4.25" notepads. I also made one 4" by 2.5" mini notepad.
You can also leave the paper uncut if you prefer a full size scratch pad.
Step 2: Prep your pages
Use binder clips or rubber bands to keep the pages and backing in place.
Apply a thin layer of glue using a glue stick to help keep pages together while you apply the duct tape and to add a little extra stickiness. Do not use liquid glue, it will create wrinkles and seep between the pages causing them to stick together.
