19. Sew down to the second hole and out. Stitch between the first signature and the cover, pushing your needle under the loop of thread, which makes a kettle stitch. Sew back into the hole in the second signature (fig. O). Repeat this step until you get to the last hole.

20. At the last hole, sew outward from the inside of your signature and make a kettle stitch, but do not sew back into the signature. Instead, connect the third signature by sewing into the bottom hole. Sew up to and out through the next hole and then make a kettle stitch between the previous two signatures. Sew all but the last signature this way. A couple of tips: Don’t split the thread by sewing through the middle of a previous stitch, and try to keep the tension even.
