Line baking sheet with waxed paper; place wire rack on top. Place chocolate chips in microwavable bowl. (Be sure bowl and utensils are completely dry.) Microwave on HIGH 1 minute; stir. Microwave at 30-second intervals, stirring after each interval, until chocolate is melted and smooth.
Dip one half of each pretzel rod into melted chocolate; sprinkle with, or roll in, toppings. Drizzle some dipped pretzel rods with contrasting color or flavor of melted chips. (Drizzle melted chocolate from spoon while rotating pretzel, to get even coverage.)
Place decorated pretzels on prepared wire rack; let stand until set. Do not refrigerate.
To arrange a "bouquet" of pretzels, wrap the tops of the pretzels individually in cellophane and place them in a small vase wrapped with a bow. Or, spread a few inches of crinkled paper gift basket filler in the bottom of a smooth-sided 2-quart glass jar. Stand the pretzels dipped ends up in the jar and decorate the jar with fabric and ribbon.
