Although we tinted both cotton and paper, that was more for the practice than anything, as it would be the paper that we would use on the book. The original book had not been sewn on supports but we wanted to add these in the repair for strength. The damage to the book’s spine had not actually broken clean through the hinge on either side, so we would need to work within the limitations of the original width of the casing — which, of course, did not have space for supports. So thin linen tapes, a thin linen slotted lining, and the tinted kozo were used in order to maximise the available space. And fortunately it all fit.
I had also brought another damaged case binding, which upon close inspection turned out to be hand sewn on cords before being cased in. The book is from the late 1800s, so would be a fairly early example of a case binding, before the whole process became mechanised with machine sewing. This one had bumped corners, a pretty severely skewed spine, and something that used to be living still curled up at the head of the text block against the case. First order of business was evicting the previous resident.
