First of all line two baking sheets, using aluminum foil. Set them aside.
Now arrange the small pretzels on your kitchen counter top or tray in groups of eight, radiating out in a rounded pattern. The 96 small pretzel rods will make 12 groups.
Place 2 cups of white candy coating in large microwavable bowl and microwave them until the coating melts completely. Make sure to stir the melting coating occasionally (after 40 to 45 seconds) in order to prevent overheating and burning.
Remove the melted candy coating from microwave oven and carefully scrap it into a large Ziploc bag.
Snip a medium hole (about 1/8-inch thick) in the corner of the Ziploc bag and pipe a perfect round dot into the center of each pretzel group in order to hold them together.
Starting from the midpoint (candy-coating dot), gradually draw a spiral onto the pretzels. Carry on twisting and slowly work your way out of the edges of the pretzel rods. Try you best to keep the line of the candy coating as thin enough to look like a real spider web.
Once you draw spider web on the top of the pretzel groups, leave them for few minutes to settle down.
Meanwhile, place half cup of semi-sweet chocolate chips in medium microwave-safe bowl and microwave for 40 to 45 seconds or until melted completely, stirring constantly.
Take out the bowl from oven and scrap the melted chocolate into another ziplock bag.
Make a very small hole in the corner of the ziplock bag and draw a spider in the center of the first spider web. Make a medium blob in the middle of spider’s body and repeat this simple step with the remaining spider webs.
Arrange the 12 spider webs on the pre-lined baking sheet and refrigerate for 15 to 20 minutes.
Carefully peel the aluminum sheet off, arrange on a large serving platter and serve.
