"Lay on your next section and sew it in the same way but in the reverse direction, tying up with the first loose end when you come to it. Sew the whole book in the same way, tying on a new needleful of thread as each is exhausted, making practically a continuous thread going backwards and forwards inside the sections and across the slips from end to end of the book. Each succeeding kettle stitch should be caught up by a loop (fig. 194), and it is well to catch together the loose threads crossing the slips.
"When the book is sewn, the back may be covered with thin glue and lined with a piece of leather, but as this is a little difficult to manage neatly, and as the book will hold together without it, for a temporary binding the sections may be left without glue.
"For the cover cut a piece of covering vellum[99] (vellum with a surface) large enough to cover the book and to leave a margin of 1-1/2 inches all round. Mark this with a _folder_ on the underside, as shown at A, fig. 195. Spaces (1) and (2) are the size of the sides of the book with the surrounding "squares,"[100] space (3) is the width of the back, and space (4) the width for the overlaps on the foredge.[101] Cut the corners as shown at (5), and fold the edges over as at B, and then fold over the overlaps [p349] and back as at C. Be sure to make all folds sharp and true.
"To avoid mistakes it is well to make a cover of stiff [p350] paper first, and then, when that fits exactly, to mark up the vellum from it.
"On the inside of the vellum cover, mark faint lines about 3/4 inch from, and parallel to, the creases of the back, and further lines about 1/4 inch from these. Place your book in the cover and mark the places where the slips cross these lines. Make slits in the cover there, and lace the slips through them (fig. 196), first putting a piece of loose, toned paper inside the cover to prevent any marks on the book from showing through the vellum. Then lace pieces of silk ribbon of good quality[102] through the cover and end-papers, leaving the ends long enough to tie."
_Set Inscriptions._--Ordinary inscriptions generally consist of a given number of words to be set out in [p351] a given space. Careful planning may sometimes be required to fit in the words suitably, or to adapt the lettering to the space. But setting-out (p. 258) becomes much simpler after a little practice, and the good craftsman avoids over-planning.
