Steps:
1. Cut the cloth into a circle and fold its edges together to naturally form a pleated effect, that is, "petals".
Sew three such "petals" together.
3. Choose a rag to wrap a bead and sew it in the center of the flower to become a "stamen".
4. Choose a thick flannel and cut out the shape of the leaves.
5. Pull up the center of the "leaf", don't cling to the bag, and then sew the edge next to the "flower" on the bag.
6. Sew a few lines on the bulging "leaves" as "tree stems" to create a three-dimensional "leaves" with concave-convex effect.
