Not sure how many you are going to make, but since you plan to make it a tradition as a graduation present I would stick with that. The nieces and nephews that are the age of my children, I have only made one quilt because they had either a mother or grandmother that made quilts. (The one I did make was because the family is a big Seahawks and Seattle Mariners fans so I made a quilt with those fabrics.) For their children I have been making quilts based on things they like. (I Spy quilts, Star Wars, Disney - any excuse I can think of I make them a new quilt.) I figure as they outgrow them, they can donate them.
