One of the best quilters I know is a man, married & with 3 wonderful smart kids. My dad used to make quilts; my uncle makes work quilts from old clothes.
Let him ponder it for a while & if he wants to try it, give it a whirl. Blue jean quilts are fun & easy to make. Even if it's not perfect & straight, etc., it just shows that someone took the time to make something for me.
