Take the needle from the inside of the sewn quire out and down (a) under the thread between the previous two quires (b). Bring needles up through to the new quire(c). Pass the thread under the thread (a) that was passed down. Move up to the next quire, passing the needle to the inside.

Drop thread down one quire and pass under the leather bellow the quire. Move thread back up to the same hole that the thread came out of and pass the thread back into the quire and proceed to the next station.

Likewise one can sew this way on doubled cords. Just think of the cords as the two parts of the leather.

When doing this technique, it looks best when you do each stitch the same direction throughout.

Depending on the type of binding you are doing this can be done on the inside or outside of a quire. (Generally, I Find it easier to do this on the inside.) For step by step pictures and more in-depth directions see: Smith, Sewn and Pasted Cloth or Leather Bookbinding for Book Artists Requiring No Special Tools or Equipment, pages 110-114.

To make the knot, take a new piece of waxed thread and start by making a loop with the short end over the long end. Bend the longer end close to the loop and push bend through the loop, creating the knot. Tighten the knot, not the loop, and not too much. Slip the old thread into the loop close to the paper. Tighten the knot and adjust placement. When the knot is in place give the new thread a tug on both sides (do not pull on old thread, this will loose the knot). You will feel a slight snap as the knot locks into place. Test by pulling the new thread. Release the knot by tugging on both ends of the old thread. As always, when pulling the thread be careful not to tear the holes in the paper.
