How do you make a straw ball with straws?

Snip two straws in half and stick one end of each half into a clay ball so the straws are perpendicular to the cardboard. Snip four more straws in half and stick the end of each one into a clay ball at a 45-degree angle to the upright straws. The angled straws should create an X between each set of upright straws.
