How did the girls know that Wanda liked them even though they had teased her?

Explanation

The girls came to know that Wanda liked them even though they had teased her as she had asked Miss Mason to give the green dress with red trimming to Peggy and the blue one to Maddie. Later when Maddie looked at the drawing very carefully, she realized that the dress had a face and a head, which looked like her own self. The head and face in the drawing given to Peggy looked just like Peggy. That is why the girls knew that Wanda liked them even though they had teased her.
