What did Madame Defarge bring to the carriage in A Tale of Two Cities?

In chapter 6, Dr. Manette, Mr. Lorry, and Dr. Manette's daughter, Lucie, step into a carriage set for London. They decide to leave France because France is too dangerous a place for them to stay.
Dr. Manette, once inside the carriage, asks for his shoemaking tools as well as the unfinished shoes he is in the process of making. He says that he learned to make shoes while he was a prisoner in La Bastille. He was in La Bastille for eighteen years and spent much of that time in solitary confinement. Making shoes was his way of keeping his mind occupied.
At this point, Madame Defarge momentarily stops knitting and goes to fetch, and then brings to the carriage, the shoemaking tools and unfinished shoes that Dr. Manette was asking for. Dr. Manette, imprisoned for so long, still thinks that he is in prison.
