Padded Boards

This was actually the first book I'd encountered in the lab with padded boards. The cover material felt like paper lined vinyl. The material was cracked in a few places and was coming off the padding. The spine had almost entirely deteriorated. Luckily, the sewing, original mull lining, and joints were in tact.

I removed the covering material gently with a spatula. Next, I lifted the endpapers at the turn ins. This was relatively easy because I went under the original cover material turn ins. Then I took off the few remaining bits on the spine. I pasted out the spine and lined it with Japanese tissue, then linen (PVA). The padding was only attached by four tiny dabs of glue, so I was able to fold it back on itself and bring all the new materials on to the boards. I also added a new spine piece of linen lined Morike and a stiffener, to make the spine more durable.
To recover the book, I used a sheet of Morike. I glued it down only at the spine and the turn ins, to prevent damage to the padding. Finally, I glued the original covers on the Morike (PVA). I did not bother to tone the Morike because I was afraid it would do more harm than good.
