Step 5Drill holes for EL wire
iImage Information

Decide where you are going to drill a hole or holes in the plastic, to thread the EL wire through, from the back, and drill the holes. The holes should be about the same size as the EL wire. For this project, I found that a 1/16 inch drill bit works perfectly for 1.2mm angel hair. (I also discovered that 1/16 inch drill bits can break easily, so that you have to stop what you are doing and go to the hardware store.) Obviously, you want the hole to be as small as possible, while still allowing the EL wire to pass through it, because you don't want the hole to be visible. Some designs may require several holes, such as those requiring more than one color of EL wire. The biohazard project required six wires/six holes.
