The repaired textblock was placed into a finishing press and the extant thongs were oversewn using alum tawed calf skin over linen braid. The sewing used 40/3 thread, packed around the thongs.

Given the hard and inflexible nature of the vellum on the wrapper, it was determined that aero cotton would permit a greater bond between the new and the old. However, for small patch repairs on the flat areas of the spine (where the vellum had tear running perpendicular to the joint), vellum, pared thinly along the edges, was used.

After the inner joints were reinforced, the textblock was laced into the wrapper. The lacing in of the thongs and braids created a great amount of tension on the joint, necessitating the use of an outer reinforcement material. This overlay was formed of 15% gelatine size used in conjunction with goldbeaters skin. The goldbeaters skin was wiped with acetone to degrease, then cut into strips the length of the wrapper between each set of lacing holes and wide enough to extend onto the spine edge and beyond the line of weakness created by the lacing holes. A layer of goldbeaters skin was also adhered over the section of the spine at the head, above the top lacing holes.
