Re: Sewing Frame

As Jack Thompson points out, a sewing frame isn't necessary for a single
book sewn on cords. In fact, it's a labor-saving device that came centuries
after the supported-sewn codex structure was developed.

As far as keeping tension on the cords - not so. After the initial 2 or 3
signatures are sewn, they form a jig to hold the cords in place and the
sewing is quick and easy. Vertical tension on the cords is unnecessary
because the sewing thread wrapping around the cord creates a cable
structure to the cord. This "cablizing" of the cord creates a continuous
hinge that is much like a spring or slinky allowing for smoothe hinging of
the book through its successive openings. By packing the sewing, a more
uniform cable is created. But again, no frame is necessary for this kind of
structure.
