Looking for a way to make printable books with real pages I was happy with for my dollhouse, I finally settled on a combination of folded booklets a lot like the ones you learned to make in school but with more pages, and a folded bookcover.
Start with a rectangle that is twice as tall as you want your finished pages to be, and 8 times as wide.
Fold in half lengthwise, open, then fold into 8ths, by folding in half cross wise, then folding each half of that in half, and in half again.Open it out. You now have a piece of paper seperated into 16 parts.
Now fold in half again,short ends together, and cut on center lengthwise line up to the last pages, indicated with the solid red line.

Unfold, and fold in half lengthwise, start folding out the pages on the folds made in step one, finished it should look kind of like this from the top, the red lines are the folded edges of the first and last sets of pages on the paper, the black lines are the cut edges.

Fold pages over to form booklet with 8 pages.

Now on to the cover.
Making the book cover, start with a rectangle just a little over twice as wide and twice as tall as the booklet is open on it. Fold top and bottom edges towards center, and make sharp creases in the center to make the spine.

Then fold the covers in half, so they meet up with the spine of the book.

Insert front and back pages of the booklet into the pockets formed by the cover. After you are done with that, you may want to put a real book on them for a little while to flatten them out a bit more.

Here's a printable journal to try it out for yourself with the fold lines clearly marked. I LOVE this technique!

Here's some other printable books to assemble. They will open in a new window.
