Put your candy melts in a microwave safe bowl. Heat and stir at 20 second intervals, until almost completely melted. Leaving some lumps, start stirring until all melted and smooth. Add Add the shortening or oil to thin it.
Spoon or pour into the molds.
You will need to get the bubbles out. Do this by lifting the mold, and dropping in back to the surface. Do this a few times, you will see the bubbles rise, then disappear.
Measure and set out all ingredients you will be using.
Line a cookie sheet or flat tray with parchment paper or wax paper. Choose a size that will fit into your refrigerator.
Using a microwave safe bowl, add chocolate and heat in microwave for 25 second bursts. Make sure to stir in between. When it's almost completely melted, but still has lumps in the chocolate, take out and stir. By removing it before it's completely melted will ensure it doesn't burn. You don't want to burn your chocolate. Continue stirring until well mixed, and cooling down to room temperature.
Slowly pour the chocolate onto the parchment or wax paper. Using a spatula, or the back of a large spoon, stat to spread it out evenly. Spread this to about 1/4 inch thickness.
Start adding your candy decorations. This is random, so make it however you like.
Now take your orange candy melts, and melt them the same as you did the chocolate. Careful not to burn them. These tend to be on the thicker side than chocolate, so add the shortening or oil a little at a time until dissolved. your candy should have a thinner consistency and easy to drizzle.
Pour or spoon the melted candy melts into the baggie, pouring into the corner tip. Twist the end, so it doesn't leak out. With your scissors, snip a very small piece from the tip. it may leak when you cut it, so hold it over the bowl.
Now you're ready to drizzle it over the chocolate. This is your design, so get creative.
Put in the refrigerator for 30 minutes or until cooled and firm.
