A round blanket with the pattern of a pepperoni pizza on it. Bought it as a funny treat for my wife and me. Our, now, 5yo sleeps with it every night. It's his pizza blanket!
I've almost pulled the trigger on a tortilla blanket for my wife, as she always wraps herself in the blanket like a burrito, but I'm afraid I'm the only one that will find it funny.
Do it. It's soft and lasts forever, even with an infant to 5yo. It has only started to see some minor holes but my kid likes picking at holes so he is likely making it worse.
