I'm sorry for your loss-I agree with what everyone else has said about sorting by craft and using tubs and shelves. If there ae unfinished projects that you just can't bear to throw away pack them away for awhile. We just moved again & this time I went thru every box in storage & finally made myself get rid of my mother's stuff and she died 20 years ago. My aunt, on her deathbed gave me 1.5 yards of muslin that she had bought to make cafe curtains in the 50's. My children have started really pushing us to get rid of excess becasue they don't want to be stuck with it when we die.
My local long arm quilting friend and her quilting group just finished a bunch of quilts that a friend of theirs had started before she died. She left journals with her plans and they finished them to give to family members-it has taken them a year but what a gift of Love!
