Cover a baking sheet with parchment paper and set aside. 

Place each color of candy melts into a separate resealable sandwich bag, but do not seal shut. Place all bags into the microwave and microwave on 50% power for 60 seconds. When cooking is complete, knead each bag. Return to the microwave, heating at 50% power for 60 seconds and kneading until smooth. 

Some of my colors seemed to melt quicker than others and I'm not sure why. If your candy melts just need a little more, place them into the microwave for 30 seconds at 50% power. 

Seal each bag shut and snip the tip of one color and add dollops onto the prepared baking sheet in random places. Repeat until all bags are empty and all colors are on the baking sheet. Drag a knife into the melted candy to swirl and spiral the colors. Sprinkle with rainbow jimmies, candy stars, and silver sequins. 

Let stand for an hour to harden or refrigerate for 15 minutes until hard. 

Score the candy bark with a sharp knife and break apart. Serve immediately or cover and store at room temperature.
