I am glad I have found this napkin:
This was her first remembrance from the Moor:
My wayward husband hath a hundred times
Woo’d me to steal it; but she so loves the token,
For he conjured her she should ever keep it,
That she reserves it evermore about her
To kiss and talk to. I’ll have the work ta’en out,
And give ‘t Iago: what he will do with it
Heaven knows, not I; I nothing but to please his fantasy.

– William Shakespeare

Othello, Act 3, Scene 3. Emilia shows blind loyalty to her husband Iago when she steals Desdemona’s handkerchief for him. But that will later change when she discovers Iago’s treachery and she abandons her loyalty to him for the sake of truth and justice. Emilia’s speech to the audience marks the beginning of the important handkerchief plot, in which a seemingly harmless item will be used by Iago to bring about the demise of both Desdemona and Othello.
