I think it's a good idea to make a plan for your stash. Mine would go to my one daughter and she can do whatever she likes with it.
When my neighbor found out she had terminal cancer she told me she was giving me all her fabrics. I insisted that there was no hurry and that maybe her two daughters would want it after all. They didn't, so I accepted it. I've made several things using her fabrics. My favorite is her Laurel Burch pieces. The dear lady is still with me through her fabrics.
