Here’s a HOW TO on making those sturdy board books people tend to give kids when they’re younger…Cut 5″x5″ boards from pressed cardboard. I used Bienfang illustration board but any pressed (not corrugated) cardboard that’s about 1/16″ thick will do. You’ll need enough for the interior pages, plus the front and back cover. Round two of the corners…To protect the pages from smudging, cover them with clear adhesive sheets. I used JM laminating sheets. Link.
