Nay, but be wise: yet we see nothing done;
She may be honest yet. Tell me but this,
Have you not sometimes seen a handkerchief
Spotted with strawberries in your wife’s hand?

– William Shakespeare

Having come into possession of the item, Iago intends to plant it in Cassio’s lodgings to frame him and Desdemona for adultery.
