===Forming quire===
From the Carolingian period to the end of the Middle Ages, different styles of folding the quire came about. For example, in continental Europe throughout the Middle Ages, the quire was put into a system in which each side folded on to the same style.{{clarify|date=October 2020}} The hair side met the hair side and the flesh side to the flesh side. This was not the same style used in the British Isles, where the membrane was folded so that it turned out an eight-leaf quire, with single leaves in the third and sixth positions.<ref name="Intro" /> The next stage was tacking the quire. Tacking is when the scribe would hold together the leaves in quire with thread. Once threaded together, the scribe would then sew a line of parchment up the "spine" of the manuscript to protect the tacking.{{citation needed|date=November 2018}}
