Leaves need for actually building a cigar:
wrapper: good quality leaves with relatively large stretches of unbroken lamina, preferably with thin subveins.
binder: strong leaves, not necessarily smooth or unblemished but it helps
filler: leaves, partial leaves, scraps at least as long as the cigar will be.
