- 1/16"-thick pressed cardboard (Elmers or Bienfang illustration board) - 1 per leaf
- Full-sheet adhesive labels (Avery or similar) - 1 per leaf
- Card stock - 2 small strips
Step 1: Cut Boards
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.
Step 2: Print Interior Pages
Print 10-1/2" x 5-1/2" images on adhesive paper, one for each pair of facing pages. The first image will be the inside of the front cover and the first page; the next is the second and third page, etc. I used Avery full sheet labels for this. The outside 1/4" of the image will be trimmed off, so keep any content away from the edge. Cut down each sheet to roughly the size of the image.
Step 3: Mount Interior Pages
Peel of the backing from the first sheet and lay it face down. Place two boards on top, lining them up with the center of the sheet.
Trim off the excess adhesive paper using a sharp knife.
Continue mounting all interior pages, using the back of the previous page for the front of the next.
Step 4: Print Cover
Measure the thickness of the book so far. It should be about 1/16" x the number of pages. The size of the image for the front cover will be 10", plus the thickness of the book, plus any border. The image should be, from left to right, the back cover, the spine and the front cover. Print the image on adhesive paper. Crease the paper along the edges of the spine.
If you can't print a single image large enough for the entire cover, you can print it in two pieces, overlapping on the spine.
Step 5: Mount Cover
Peel the backing off the cover sheet and lay it face down. Cut two strips of heavy paper (card stock), each the width of the spine. Press them onto the adhesive paper, one along the spine, one next to it on the back cover.
Set the book on the cover, lining up the spine. Wrap the front and back cover around the book. Trim off any excess paper. When the book is opened, the cover should pull away from the book along the spine and a narrow strip of the back cover.
