After cutting cheese sticks in half, start making small slices in the cheese about half way down; don't go too far up, since you'll need to cut a whole in the top.
Pull slices apart to create the broom effect.
Using a large toothpick, create a whole in the top of the cheese for the pretzel stick.
Press pretzel stick into the cheese.
Wrap the cheese with 1 chive; make a knot, with the chive, and serve
