Use an approximately 8-inch diameter bowl to trace circles onto wax paper. Cut out and place wax paper circles on cookie sheets and arrange 8 pretzel sticks on each circle so that they are touching in the center and radiating outwards.
Melt the candy coating according to package directions (do not overheat). Stir until smooth and transfer to a gallon-sized heavy-duty/freezer plastic bag. Snip a 1/4-inch hole in the corner of the bag and pipe a flat circle in the center of the pretzels where they meet. Starting at the center and working outwards, make a spiraling line across the pretzels until a spiderweb look is achieved. Stop before reaching the tips of the pretzels so that they stick out a bit beyond the outermost ring. Pipe over the outermost ring several times in order to make it thicker, so that the sprinkles have a place to adhere.
Pour sprinkles in a bowl and use a small spoon to carefully pour sprinkles over the thick outer ring of the spiderweb.
Place chocolate chips in a microwave safe bowl and heat in 30-second increments, stirring well in between, until chocolate is melted and smooth. Transfer melted chocolate to a small plastic baggie and snip a tiny hole in the corner of the bag. In the center of each spider web, make a spider by starting with the legs. Draw a thin plus sign (+) topped with an X, which should end up looking like 8 small legs. Fill in a small circle of chocolate on top for the spider's body. Place two tiny sprinkles on top for eyes.
Allow webs to dry for several hours until completely set. Carefully peel spiderwebs from wax paper (if you are able to do so without breaking), or serve directly from wax paper circles.
