I'm basically in agreement with the group. I've had to deal with a lot of deaths in my family the past few years, though none under those circumstances. We all grieve differently and it's hard to imagine how I would feel if any of my family passed due to suicide. I would make a comfort quilt for your SIL. Use her favorite colors or colors in her home for a good fit. Give her some time and you'll have to gauge when the time is right to bring up the idea of a memory quilt. Someone mentioned a month, but that's really very soon after a death. The element of shock really does impact the grieving process in unpredictable ways. My deepest sympathy to the family.
