etymonline
crease (n.)
1660s, "long or thin mark made by doubling or folding," altered from creaste "a ridge," perhaps a variant of crest (n.), via meaning "a fold in a length of cloth" (mid-15c.) which produces a "crest." In sports, first in cricket (1779), where originally it was cut into the ground. As a verb, "to make creases in," from 1580s. Related: Creased; creasing.
