My condolences on your loss. I have no idea why this popped into my head as I read your posting, but here's one person's way of coping with the loss of his loved one. George Burns and Gracie Allen, according to him, had twin beds. After her death he was unable to sleep until one night he got up, went into her bed, and feeling especially close to her presence he found the solution to his problem.
If you and your husband used to sit and quilt together and each had his/her own space, give it a try. Move to his space and see if it gives you some comfort. And when you're ready you can start sorting and re-arranging knowing he's still there with you.
As I said, I don't know why I thought of this but hope it gives you something to think about. Sent with best wishes.
