Click on the image for the pattern, and print at fit to page. It will stitch up to be about 10 inches wide in 14 count fabric. Since it's only one color, I think shaded threads would look lovely.
When I was younger, I kept a picture of Mother Teresa on my fridge. It was a reminder to be more patient, to try to be understanding. Because she was human and did so much good, she inspired people to be better than they would be normally. She's still absolutely one of my heroes.
I'm not Catholic, you don't have to be to learn something from her.
When my daughter was a lot younger, she read EduManga: Mother Teresa (Amazon.com affiliate link), and while it's not a complete biography, it's a good overview of her life for people who don't know much about her.
