Preparation Steps

Original Recipe Text

The binder is instructed to mark the spine-folds of the gatherings on the exterior using ink (p. 89). This is done before sewing to create two lines that serve as a guide for the path of the sewing thread (p. 89).

Evidence

"Before the gatherings are sewn Sufyani suggests to mark the spine-folds on the outside with ink, in two lines, where the sewing thread will pass."

Remarks

This functional use of ink as a layout tool for bookbinding is noted in the 1619 treatise by al-Sufyani, who worked in Fez (p. 88-89). This step precedes the flattening of gatherings and the sewing process.
