Graham's crochet - Pot holder

Look what Graham made all by himself!  At first I thought it was suppose to be a coaster but then it got larger.  So I am assuming that it's now a pot holder:

Do you notice the little hole (top center)? He said he intentionally put there so you can hang it up.  Amazing how he was even thinking about that!  He has started another crochet project.  I wonder what it will be... :-)
