So sorry for the loss of your sister. Prayers and hugs to you and your family at this sad time.
I guess I am in the minority...when I die, my family can do as they please with all my stuff. Yes, I have a few things to give to my sons and stepdaughter, but no one in my family is a quilter (or even crafty), so I can suggest what to do with my sewing things, but it is truly up to them in the long run. Just my opinion.
Again, my condolences on your loss.
