Why do you think Aunt Jennifer’s hands are ‘fluttering through her wool’ in the second stanza? Why is she finding the needle so hard to pull?

Aunt Jennifer’s hands are ‘fluttering through her wool’ because she is an old lady on whom age has taken its toll. The fluttering of Aunt Jennifer’s fingers also signifies her oppressed mental condition which makes it difficult for her to even pull an ivory needle while embroidering.
