So sorry for your loss. I can not imagine how you feel. Lots of good suggestions here.
I lost my Mom earlier this year. She is with me more then ever. I live 2000 miles from her; she had been in a nursing home many years. My brother cleaned her apartment when she went to nursing home. Little things that I would have liked to keep are gone.
However I asked for and have her sewing machine.Little did I know then how precious it would become to me. The machine sat neglected for many years. Last month my machine needed to be hospitaslized and a quilt needed finished. I dug out Mom's machine a 1957 Singer 320. DH took apart, cleaned oiled. It worked better then new. Quilt came out almost flawless. It was as if Mom was guiding my hand and the machine. Quilt was for her granddaughter, my niece. Long and short, when the time is right you will know. Do not force healing. If tears come, thats ok. You are healing. The emptyness will always be there, pad it with quilts.
Many hugs
