Genesis 3:7

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.

1. As a result of eating the fruit of the tree of the knowledge of good and evil, Adam and Eve felt embarrassment at being naked. There is the unanswered question of how they were introduced to this concept of nakedness - did it just occur to them, or did someone like the serpent tell them?
2. Adam and Eve sewed fig leaves together and made themselves aprons.
3. Prior to eating the forbidden fruit, Adam and Eve were apparently innocent like little children.
4. Unless Adam and Eve had become sewing experts, sewing aprons from fig leaves must have required some time, since fig leaves are not generally huge. There is the unanswered question of how they sewed the leaves together.
