Step 1 Melt the chocolate chips in a bowl set over a pot of simmering water, stirring occasionally until the chocolate melts completely.
Step 2 Meanwhile, line a couple of rimmed baking sheets with parchment paper. Place each candy decoration in a separate large bowl.
Step 3Hold a pretzel rod over the melted chocolate. Use a spatula or spoon to drizzle chocolate over the rod, then spread the chocolate so it evenly coats the rod in a thin layer. (Leave a couple of inches free of chocolate at the bottom of the rod to grasp.)
Step 4Acting quickly before the chocolate hardens, use separate spoons to sprinkle the candy decorations over the chocolate coating. Repeat until all the rods are coated and decorated. (You should have enough chocolate to thinly coat the rods; melt a little more if you run out.)
Step 5Set the decorated pretzel rods on the baking sheets when finished. Allow chocolate to harden and dry before storing or packaging.
