Today’s simple series of folds will produce an insert that adds six pockets to a book. Start with a sheet of paper twice as wide as a single page in your book and more than four times as long. Fold in half lengthwise, then score a line horizontally. The distance between the top of your paper and the score line should be the same as your page height.
Open your paper flat, then fold the top edge down along the line you just scored. Fold the new top edge down so that the new top fold is the height of a page from the new bottom fold. In the image below the green pointy finger at the top indicates the second (double) horizontal fold, the pink one indicates the first (single) horizontal fold, and the yellow pointy fingers indicate edges of the paper.
In side view your paper will look like this. Trim off any excess paper so that the new cut edge matches the bottom folded edge.
Rotate the paper 180°, flip it horizontally, then fold the top layer down.
Fold the lower corners in to the middle. Leave a small space in the middle to allow your insert to fold more easily when it is complete.
Fold the point back up. Using the sides of the point as guides, score a diagonal line on the second (white in the model) layer on either side of the point. Turn the corners of the lower (white) layer under.
You can stop at this stage if you want. In this form your pocket insert could act as the cover for a pamphlet.
If you want to use this as an insert somewhere inside a book, you may choose to trim the remaining corners. Again, use the diagonal edges of the point as guides.
Like yesterday’s pockets, this structure can be sewn in as a signature anywhere in a book, or used as the outer layer of a signature or pamphlet.
Tomorrow I will show you a different six-pocket insert.
