I am so sorry for your great loss....so sad..... a Tshirt quilt (if he wore alot of Tshirts with logos on the front) is a great idea....or a scrappy one out of his cotton shirts and jeans is another one....the label for something like this is what I always have trouble with....what do you put on a label to express your feelings and yet comfort at the same time? That might be something someone else can help you with too.....I'm not much good with that part.
Here is a link on memory Tshirt quilts
