¾ leather, remainder of boards covered with marbled paper
16 ¾” tall x 10 ½”wide x 2” thick
In the case documented, the objective was to join textblock and detached boards, without any elaborate conservation treatment.
Board attachment by means of joint-tackets was chosen. To protect the joint-tackets and open joint area, solid dyed Japanese paper was applied.

Materials and Tools used:

Kizukishi
Sekishu
Solid dyed Japanese Paper
Linen thread 20/2, right twist
Thin metal wire as threader
Awl with a needle approx. 1mm thick

Considerations
Preconditions for board attachment through joint-tackets are met:
Volume was laced into boards
Pronounced shoulders
Fairly strong paper
Solid boards


TREATMENT DESCRIPTION

TEXTBLOCK

Since the spine has no decoration and the leather is relatively brittle, i decided to lift only the spine label, in order to hide a tacket.

The size of the book, determined the number of tackets (7). The number of holes for the lacing-in-thread, are distributed as evenly as feasible, along the spine. I make sure not to position a hole at the kettle stitches, nor at the positions of raised bands.

The thread chosen is thick enough to lie tightly in the hole made with the awl.


BOARDS

Along the spine edges, board plus leather edges are first covered with Japanese paper. Position of the tackets is marked corresponding to the spine. Two holes each are made at one tacket position to accommodate the open ends of the thread.
