1-Covers should be the same size as the score pages, since the binding is unsupported; so the . The pages will need to rest on the shelf at same level as the cover sheets.
...
4-Mark three holes on the first page or cover, spaced evenly along the gutter, no more than 1 inch from the spine edge, but no less than 1/4 8 inch, and punch with an awl or small hole punch. Use that page as a template to punch the remaining pages (about 1 to 3 at a time depending on tool). Each hole is counted as one station.
...
6-Lay down the cover, holes towards you. (I like to set the remaining pages on end, so I simply have to flip them down to the table top without worrying about getting them out of order. Run )
From the inside (or top), put the needle through the first hole, from to the inside (top) to outside (bottom), ; tighten the threads, and tie the threads together into a knot close to the inner hole. I usually tie two more knots in the same place, for extra longevitysecurity. Repeat this step for each station.
...
7-Then, take the needle thru the cover, this time from the outside to inside, and exit to the left of the other first threads.
...
8-There should be two loops visible on the outside of the cover.
...
9-Put the first page on top of the cover; and put run the needle through the first page from the top, coming out between the first page and the cover. Exit to the left of the other threads.
...
19-Then tie a knot close to the hole in the cover, tie two more knots to completely secure it, and tighten all the knots.
...
22. Cut a piece of binding tape to the same size as the height of the score. Next measure the thickness of spine face without compressing it and mark it on the tape; this portion will be left unglued to form a hollow spine.
...
23. Spread glue on each side (but not the hollow part), making sure ; try not to get glue in the center. Press down tape on the front, then turn the score over and press down the tape on the backcoverback cover. The threads will form slight swellings at each station.
...
24. Final step: cover the knoted knotted ends of the threads on the inside front cover and inside back cover with clear book tape. Ta da!
