I just need help. How did Alice Walker bring heritage awareness in the short story?

Alice Walker increases our awareness of the concept of heritage by juxtaposing Dee's idea of heritage with Mama and Maggie's.
For Mama and Maggie, heritage is something alive, something present. It is using the butter churn with pieces whittled by uncles; it's sitting on the benches dad made that have "rump prints" from years and years of use; it's using the quilts made by aunts and grandmothers; most of all, it's knowing the stories of all of these people and keeping them alive through the use of these items.
For Dee, on the other hand, heritage is something you hang on the wall; it's something distant and past, something to be preserved and not used.
When Mama tells Dee that she has promised the quilts to Maggie, Dee is horrified because she thinks Maggie will be "backward" and put them to "everyday use." Mama doesn't understand why Dee would hang a quilt on the wall or why she would insult Maggie for using what was made to be a blanket as a blanket. The conflict here comes from the fact that Dee has a very different, somewhat shallow, idea of what heritage is and means.
