Take a piece of paper or a blanket or something lying flat, with an object lying on top of it. Now the paper/blanket is folded up to wrap the object. What were the opposite sides of the wrapper now meet in the middle on top of the object, or they may overlap but there will still be an end-point of the wrapping.
What is a word for where they meet? i.e. where you could put your hand under/inside (assuming it wasn't taped together) to unwrap it again.
The closest I can think of is
seam but that doesn't strike me as correct.
Sample sentence: "Holding back his excitement, Aloysius carefully inserted his hand under the XXXX of the wrapping paper and slowly unwrapped his gift"
