Knitting and wine are elementary symbols to understanding A Tale of Two Cities.

Madame Defarge, the Vengeance and the mob seek revenge for the numerous sufferings caused by the hands of the French aristocracy. Even though they want to promote happiness and peace, ironically, they instead produce more violence and oppression. Not realizing that their undeniable violence towards the nobles was the same as what the nobles had done to them show how the peasants turn out to be as appalling as the nobles.
