Oh Haaale NO!
Mrs. Hale is the character fighting to be heard, while Mrs. Peters is more reserved. What strikes me as interesting about these characters is they are never given first names. One reason for this could be that it's an illustration of these women "belonging" to the men they are married to. In that case, it reinforces the feeling Mrs. Wright had about being trapped as merely an extension of this man with no way of making a happy, "cheerful" life for herself. A different reason could be that these two women are the two sides of Mrs. Wright. You may think of Mrs. Peters as the side that was on the surface, very agreeable, stands behind her husband and doesn't make trouble. On the other hand Mrs. Hale is what is bubbling below the surface. The side that takes exception at being condescended to and desperately craves equality and respect.
"quilt it or knot it"
They keep bringing it up almost as a little joke, so it must mean something. What is the significance? When looking into knitting you find that to "quilt" takes a lot of effort but makes the quilt incredibly durable. One piece should be completed by multiple people at once, while "knotting" is a much quicker method that can be done on your own. The obvious correlation of the "knot" would be that Mr. Wright was killed by a knot around the neck. But if you look deeper, you see that if she were going to "knot it" as the ladies implied she would, it again speaks to her intense isolation from the world. Finishing the quilt by herself, because she has no circle of friends to help her.
