I am so sorry for your loss.
He was your husband and you should do whatever you want with his clothes. To me, it would be very comforting to piece them together into a quilt to keep "me" warm. Making it and using it is going to trigger happy moments. Wjhat could be better than that?
And remember, your daughter is trying to handle her grief, too. But, ultimately it's your call---you are the wife.
