kettle stitch
See
illustration The stitch made near the
head and tail of a book sewn on tapes or cords,
and which holds the sections (other than the first
and last) together. The term may be a corruption
of "catch-up stitch," or "Kettel stitch" (the
stitch that forms a little chain). Sometimes
called "ketch stitch." (106 , 56 , 236 )
