Spread the pretzels out in a circle, with the loops facing outward, in a double layer.
Melt the chocolate wafers in a bowl in the microwave in 15-second intervals, stirring in between, until mostly melted, then stir continuously until fully melted (so as not to burn the chocolate).
Pour the melted chocolate over the inside half of the pretzels, all the way around in one continuous pour. Immediately sprinkle on the Christmas sprinkles, so they stick to the chocolate.
