Step 4: Eye & Mouth Holes
Carefully measure out and mark up the holes for the eyes, mouth, and base opening on the mau5 head. (The base opening should be centered where the air plug was.) Using a utility knife, cut out the holes. I found that a “punching” technique worked best for cutting the thick material: punch the blade in, pull out, go a little distance, repeat as you go gradually along your cutting lines.
