puckered leather
Leather which, while still tractable, during the
covering of a book is pushed into wrinkles or
folds, induced at times by thinning leather on the
flesh side in areas where folds are required.
Sometimes higher folds are so located as to take
the wear and abrasion such bindings are likely to
suffer, thus protecting the remaining surface
areas of the covers. The leather is first
impregnated with paste which, when dry, imparts a
high degree of rigidity and solidity to the fold
areas. (311 )
