The first and last sections are overcast usually with cotton or very fine thread. The first sheet is now to be laid against the bands, and the needle introduced through the kettle stitch hole on the right of the book, which is the |25| head. The left hand being within the centre of the sheet, the needle is taken with it, and thrust out on the left of the mark made for the first band; the needle being taken with the right hand, is again introduced on the right of the same band, thus making a complete circle round it. This is repeated with each band in succession, and the needle brought out of the kettle stitch hole on the left or tail of the sheet. A new sheet is now placed on the top, and treated in a similar way, by introducing the needle at the left end or tail; and when taken out at the right end or top, the thread must be fastened by a knot to the end, hanging from the first sheet, which is left long enough for the purpose. A third sheet having been sewn in like manner,[2] the needle must be brought out at the kettle stitch, thrust between the two sheets first sewn, and drawn round the thread, thus fastening each sheet to its neighbour by a kind of chain stitch. I believe the term “kettle stitch” is only a corruption of “catch-up stitch,” as it catches each section as sewn in succession. This class of work must be done very neatly and evenly, but it is easily done with a little practice and patience. This is the strongest sewing executed at the present day, but it is very seldom done, as it takes three or four times as long as the ordinary sewing. The thread must be drawn tightly each time it is passed round the band, and at the end properly fastened off at the kettle stitch, or the sections will work loose in course of time. Old books were always sewn in this manner, and when two or double bands were used, the thread was twisted twice round one on sewing one section, and twice round the other on sewing the next, or once round each cord. In some cases even the “head-band” was worked at |27| the same time, by fastening other pieces of leather for the head and tail, and making it the catch-up stitch as well. When the head-band was worked in sewing, the book was, of course, not afterwards cut at the edges. When this was done, wooden boards were used instead of mill boards, and twisted leather instead of cord, and when the book was covered, a groove was made between each double band. This way is still imitated by sticking a second band or cord alongside the one made in sewing, before the book is covered. The cord for flexible work is called a “flexible cord,” and is twisted tighter and is stronger than any other. In all kinds of sewing I advise the use of Hayes’ Royal Irish thread, not because there is no other of good manufacture, but because I have tried several kinds, and Hayes’ has proved to be the best. The thickness of the cord must always be in proportion to the size and thickness of the book, and the thickness of the thread must depend on the sheets, whether they be half sheets or whole sheets. If too thick a thread is used, the swelling (the rising caused in the back by the thread) will be too much, and it will be impossible to make a proper rounding or get a right size “groove” in backing. If the sections are thick or few, a thick thread must be used to give the thickness necessary to produce a good groove.
[2] As each thread is terminated, another must be joined thereto, so that one length of thread is, as it were, used for a book. The knots must be made very neatly, and the ends cut off, or they will be visible in the sheet by their bulk.
