The novel ends with Esperanza teaching Isabel how to crochet the zigzag stitch. How do the “mountains and valleys” compare to the plot of the novel?

The mountains and valleys symbolize the obstacles one faces when starting over..... the instruction she gives Isabel mirrors the lessons she learned from her grandmother and the advice she was given.

It also shows the struggles Esperanza has gone through, when she gets to the top of a mountain she has good luck, when shes at a valley something bad has happened.
