Look at all the pleasure you give those grandkids. I made so many costumes and they still remember. AS someone who was always hesitant to "waste" money on myself it was amazing when I decided It was my turn and bought my Bernina. I have enjoyed every minute of having it and refused to feel guilty about it. If you are 64 you've spent a lot of time and effort on others. GET your MACHINE and get the one YOU WANT. It does not need to be justified! And when you get it take pleasure in having it ----no guilt feeling!
