What do the butter churn and dasher symbolize for the narrator in "Everyday Use" by Alice Walker?

To the mother, who is the narrator of Walker's story, the butter churn and the dasher are useful items made by her relatives that are part of their everyday use. They are symbolic reminders of the family members who made them.
Not long after her arrival, Wangero walks around the house, viewing the various items, deciding what she can select for her collection of "heritage" items. Moreover, she feels that she has the right to take whatever she wishes. She looks at the benches that have become worn where family members have sat. Finding them quaint, Wangero says to Hakim-a-barber,

"I never knew how lovely these benches are. You can feel the rump prints."

At last, she sees what she wants. Running over to the corner where the churn stands with the milk already in its clabber, Wangero studies the churn and the clabber. Having told her mother that she needs the churn and its top, she asks if their uncle Billie had whittled it from a tree that used to be in the yard. The mother replies with a taciturn "Yes."As explanation for her wanting these items, Wangero informs her mother that she can use the churn top as a centerpiece for her alcove table; later, she will think of something "artistic" to do with the dasher. Then, she goes to the trunk that sits at the foot of her mother's bed and rifles through it for more "artistic" items; she pulls out two quilts. But, the mother refuses to let these items become mere "artistic" touches. She grabs them from her daughter and gives them to Maggie, who will put them to everyday use, instead.
