First of all a signature is a series of pages that fold together to form part of the book. If any signature is more than four pages (signatures are always mulitiples of 4 if you have not guessed by now) it must be sewn together to hold the pages in place. Once the sewing is completed, the signature block is then covered as was mentioned in an earlier blog. Let's start at the beginning.

Next step deals with math again. I will try to explain it easily without using too many words. First of all, one always thinks in what is called stations when sewing signatures. This is a set of two holes (in and out- back to the beginning) and is always used when there are more than 4 pages in a signature.
So where would you put your holes? Perhaps it is a good time to note that I am not schooled in book arts, I have read and reread and experimented and figured it out for the most part, so in many cases what I do is not always text book correct. Just thought you might like to know. ;-)
Now, where was I, oh where to put the holes. This is what I do and it seems to work pretty well, eventhough the stations are larger than my tapes, it all works out. Uusually, I can wait in the sitting room or sit in the waiting room and in the end I end up in the same spot so this is how I do it. I like to have about .5" to .75" for my first hole of the first and last stations. These are the holes that start from the top and bottom edge of my text. So, I must first add in the amount of paper I plan to trim off from each side. If that amount was to be .5" and I want my first station to be .5" from the edge of my text- my first hole of the first and last stations would be 1" from each end of the sheet of paper used to print the text. Note illustration. Next, I move my ruler so that it starts at that first hole and measure. In this text, I will have 3 stations or 6 holes. Two holes have already been determined so 4 holes are left. If the distance is around 5 inches or so. I make each station 1inch. Second hole of the first and second hole of last station will be one more inch in. After finding the center mark I use that as the center to determine where the last signature holes will go. I make a mark for each hole on either side of the center mark. I don't know if I understand what I do either, but it is a start.
The text then goes to the cradle for hole punching. The folds that were so carefully made earlier make this job come out more precise. I place the signatures inside of each other, checking to make sure they are even and square. When they look good, I place the sheet of paper where I want to punch my holes on top. Next, I use a little tiny drill with a very small bit to drill my holes. Most instructional books will say to use an awl; however, the tiny drill works well for me. The signatures are now ready to go to the sewing station and be sewn together.


Where do you start to sew? I start at the back of the book and move forward. I turn the book over and then place the back page on the bottom and the folds laying next to the tapes. The tapes have been lined up so when the thread is on the outside of the folds the tapes will be included in the sewing.


Well see you all around town,
Janet
