all along ( all across, all on )
A method of sewing a book, usually by hand and
generally on cords or tapes. The thread goes "all
along," inside the fold of the section—that
is, from kettle stitch to kettle stitch of each
successive section, one complete length of thread
for each section. "All along" is traditionally
associated with the best method of sewing a book
by hand, although books were sewn TWO ON and even THREE ON when the
sections were very thin or when an economical
method was required. The term is also used,
somewhat incorrectly, to describe machine book
sewing when each section is sewn with the full
number of threads. Also called "one on" and "one
sheet on." (236 ,
