OK so I realized that the photos from Friday were not great and the whole process might be a little confusing. I wanted to make another so I did and tried to take some better photos. In the process I had a few ideas that I may try, which I think will make the book even more interesting.
You will need two folios of six sheets each, folded in half and nested. I made mine 4 x 6 inches then trimmed so the inner pages did not extend past 4 inches. Ideally you will have a long sheet of cardstock weight paper that is just a bit over the height (maybe 6 1/2 inches) and 4 1/2 x the width of your book. Three or four times the width is workable. We don’t all have huge sheets of paper or card hanging about. My sheet was just about 16 inches wide, and I made it work!
Folding the cover.
Fold the cover in half, then fold one side back, leaving 3/4 inch of the cover from the original fold. Fold the other cover side to match.
Open the cover and lay it out with the little pleat upward and the front of the cover face down on the desk. Add your two folios on either side like so:
Mine were cut from paper on a roll so they are still a bit round-y looking!
Grab the topmost halves and pull them up so they touch and are either side of the pleat and clamp them together like so. The covers are face-to-face, hanging down, and the inner halves of both folios sandwich the pleat.
Lay the structure down, with the outer halves of the folios and the face-to-face covers at the bottom, and just the inner halves of the folios sandwiching the pleat to the top. On something that will protect your desk (like a cork tile or self healing mat) punch your five holes for a 5-hole pamphlet stitch. Two holes, about 1/2 inch from the top and from the bottom, one in the middle, and one either side, evenly spaced like below. Does not have to be perfect!
Sew the 5-hole pamphlet stitch with waxed linen thread. Now fold the folios together with the covers around them. The pleat will be dead centre of the book.
As you can see, the sewing is all inside the book, no threads show on the outside!
Now, if you had paper that was a good 4 1/2 to 5 times the width of your book, you would perhaps have to trim. Mine was just about 4 times the width. I folded the extra in and stuck it to the inside of the cover.
Done. I think if the pleat in the middle were wider it might make a pocket. It may solve the problem of needing a very very wide strip for the cover if you used two strips, not joined in the middle, then stuck the top and bottom edges to make a pocket that way!
Likewise, you could use heavier cardstock and create pockets from the edge I folded over and stuck. I was using decent, but not heavy weight pained paper for my cover.
I think this is a really lovely way to easily bind a book with more folios/pages inside and more stability that a traditional pamphlet stitch. I just think it has a lot of potential and hope you give it a go!
