What's nice about this structure, which I am calling Wrapped Accordion, is that it can be made from one piece of rectangular paper and printed or painted only on one side. It has no sewing or glue. It has hard covers. You fold an eight-panel accordion, but it ends up with six panels. At the covers there may be a slightly uneven edge, due to the various thicknesses of board and paper, but perhaps you can't have everything.
Small size: 8.5 x 11 (or A4) paper, makes a book 1.5 x 3.5 inches
Medium size: 22" x 14" paper, makes a book 2.75 x 6 inches
Strathmore drawing paper is what I used for the example. The paper needs to be lightweight because of the folding involved. To create a different sized book, decide the size, double it for height, and add one to four inches (for the pockets that will hold the boards). For width, multiply your ideal book size width by eight.
Cut boards the size of the desired book and subtract 2 board thicknesses on the short side, then on the long side. My boards turned out to be 2.5 x 5.75, but I would recommend a thinner board than the book board I used.
Tools: pencil; metal ruler longer than your paper; X-Acto knife and cutting mat or scissors; bone folder
Inspired by the abutilon flower, I painted the paper.
When it was dry, I turned it over and measured and marked up along the short sides.
The height of the desired size book (6") minus 1/8"= 5 7/8".
Then the height of the book: 6".
Then there remainder: 2 1/8" (this could have been simply 2").
Line up the marks and score with the bone folder.
You'll ignore those marks for a moment.
Begin the folding for the eight panels.
First: fold in half to make the paper shorter and squatter.
Open it up, then fold each cut edge to the center fold you created.
Fold the edges back like window shutters.
Then complete the fan fold by matching folds to folds.
Now, turn so the tabbed edge is at the bottom.
Fold up along the score.
Fold down along the second score you made.
Open completely, and with a knife against a ruler
or using a scissors, make horizontal slits from the first
folded intersections to the edges.
You have four horizontal slits.
Fold the bottom tabs in toward each other.
Fold the center tabs in toward each other
Fold the bottom panel up. It will partially cover the center panel.
Slip the boards in the pockets made by the bottom tabs.
Fold the top panel down.
Tuck the edges around and behind the boards to anchor them into place.
Refold your fan.
And there is the Wrapped Accordion.
