I thought it was fig leaves.....maybe just a fur wrap???
And the first lesson that sin can only be covered by the shedding of blood. Hence the animal skin covering for their nakedness rather than fig leaves
They did indeed make their own covering of fig leaves but God had a better idea:
Genesis Chapter 3:
V.7 And the eyes of them both were opened, and they knew that they were naked; and they sewed fig leaves together, and made themselves aprons.
V.21 Unto Adam also and to his wife did the LORD God make coats of skins, and clothed them.
