In order to stay healthy in spirit and mind one needs to keep active, positive and open to new ideas. It doesn't matter if it cost a lot of money for your 'habit' - no - one counts the golf clubs as selfish, or how many cartons of cigarettes or beer have been consumed. You will have a lovely legacy for all to admire. Change the quilts around every week if you have to. Surely a gift is never criticised, and if you are not taking bread from someone else in order to quilt it should not be a problem. If you earned the money you can spend it how you like - there is no obligation to save it all up like a miser so that other people get the inheritance - enjoy your life whilst you can...keep on quilting (you don't need to justify).
