You're a better woman than I am! As someone upboard mentioned, what is the daughter learning if her mother is doing the asking?
Many years ago, back in the 70's, there was a fad of taking assertiveness classes. I took a class (my husband called them my aggressiveness classes) and have used the lessons I learned ever since. Just this week a former coworker for whom I had made a baby quilt when she was pregnant contacted me and asked me to make a quilt for a friend of hers who is pregnant. What? "No" is a complete sentence. You can do it too!
That being said, I love the hearts pattern of the runner and you did a great job with color coordination. She is so lucky to have it for the price of a paper clip.
