Please make sure your acrylic is masked before engraving and cutting. I recommend using white masking tape for this. Flashback can be avoided by raising the material off of the honeycomb. 

Each color has been placed on its separate canvas. 

Step 1: Cut the hearts out of 3mm red acrylic
Step 2: Cut the white sticks out of 3mm white acrylic.  
Step 3: Attach the earring hardware as shown in the photo.
