You did GOOD. Your Mom will probably never change her mind about the rules of quilting and that is ok. She simply needs to understand that you go by a different set of rules. If she starts in again on you about anything that she disapproves of you doing maybe you could tell her that while you love her very much you have chosen your own way in life and you would rather not hear about it again. My Mom is very special and never tells anyone what to do or not to do so I am blessed. But, I had to deal with my DMIL about some things while she was with us. I do miss her though. She could be sweet at times. She just liked things her way and her way usually wasn't mine. Be proud of yourself and it should be easier next time.
