I think you did the right thing. You made promises you kept, plus you helped out someone who was really interested in what you did. Which you should be really proud of! As far as she promising not to make a profit off your design, people will do what they will-you didn't get a thank you-speaks volumes as to what she might do with it. Perhaps she wasn't happy you didn't do what she wanted you to do right then and there. Tuff-school benefited and that was the plan so all is well. Beautiful pattern!
