At the headband the fold of leather, pared thin for the purpose, must be squeezed together with a folder and pulled out a little to leave an even projection that can be turned over to form a head-cap. When both ends have been turned in, in this way, the boards must each be opened and pressed against a straight-edge held in the joint ([fig. 66]) to ensure that there is enough leather in the turn-in of the joint to allow the cover to open freely; and the leather of the turn-in at the head and tail must be carefully smoothed down with a folder.
