LOL I would think that a divorce is like any other milestone in ones life. I just attended our local guild meeting where Ellen Edith was the speaker, she is from No. California. She has taken events from her life and created quilts/wall hangings & just recently came out with a small book. She is a great speaker and had us laughing through out her lecture. Check out her website. It might give you some ideas on how to get started.
Lots of luck to your niece, a divorce is tough but she will be a better person from the experience. I know I was.
