What a heartache beyond words for that family. I echo the thoughts that blue would be fine, but the hearts might or might not be well-received. Personally I would not suggest a T-shirt quilt this early on. They may need to leave things just as they are for a while..his room, his clothes, everything while in the early stages of shock and grief. The thought of cutting them up might be too harsh right now, even though the end result could eventually be quite a keepsake. That's my initial, gut feeling about the quilt plans.
