I will give my opinion both as a nurse and a recent widow. I have dealt with suicide families in the past and I think it takes a lot of time to accept the depression as a disease and not just a cowardly selfish act. I think I would not want a memory quilt at this time.
I always make my quilts and give them away. My husband had a cardiac arrest while in the hospital and did not get enough oxygen during the CPR. He was left in a "persistent vegetative state" or a vegetable for 9 months. I brought him home to care for him and there were so many times all I could do to make myself feel better was to wrap up in a blanket and hug myself. It would have meant so much more if I would have had a quilt to cuddle with. Just something about a home made quilt to bring comfort. I think a throw sized quilt or twin quilt with a nice label that might say something like "Hoping you find comfort as you wrap yourself in this blanklet of love". Just my opinion.
