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. 

This file has two layers: a red (engrave) and a black (cut). 

Step 1: Engrave the red layer onto the 3mm pink acrylic.
Step 2: Cut the black layer immediately after.
Step 3: Fill in the engraved sections using a white acrylic pen. Let everything dry before removing the masking tape. You might have to wipe off any acrylic. 
Step 4: Attach the earring hardware as shown in the photo.
