I am sorry for your loss.
There's the 7 shirt quilt:

But you can really use any pattern. I cut all my recycled shirts into 5" charms and used some patterns from the Nickle Quilts books by Pat Speth.
Here are a few examples:

And finally, the quilt need not be made from all shirts. You can add yardage in a neutral color and pick any scrappy pattern.
