She was not old at that time, but a teenager, and her cover to observe german positions was, according to article being an itinerant seller of SOAP in a bicycle.
Being a young woman, according to the wikipedia, she was also able to entertain conversations with the young german soldiers to gather more information.
It looks like the knitting kit was just a clever way of having a place to hide the OTP codes she used and keeping track of the ones already used. Also, according to the wikipedia she was once detained by the germans for interrogation, but they didn't think of checking her hair tie.
Pretty clever IMHO, not to mention the mind-boggling level of courage.
