When the skin was finally dry it was ready to be cut and turned into sheets of parchment. A single animal skin could only produce a few amount a sheets. If the leaf sizes need was smaller, then of course more sheets could be produced than if larger leafs were needed for a manuscript. Conjoined leaves, or bifolium, were made by folding a large sheet in half. Single leaves were cut from what remained of the skin after the bifolium were cut.
