Who put the needle in the poppet?

In Arthur Miller's play "The Crucible," the needle is placed in the poppet by Mary Warren, a character who serves as a servant and is involved in the witch trials. While making the poppet in court, she sticks a needle into it for safekeeping. Later, this poppet becomes a crucial piece of evidence when Abigail Williams uses it to accuse Elizabeth Proctor of witchcraft, claiming that the needle in the poppet was used to harm her.
