1) Grab your EVA and pattern out your desired design, I used a pen here. 2) With a razorblade and a steady hand, follow your design. Light pressure will give you a shallow design while a heavy hand will come out deeper. 3) HEAT IT ALL UP! EVA tends to burn easily, so do even circular motions. You'll notice the lines will begin to open up! 4) And there you have it! Super easy ajd effectice carved in detailing for all your EVA armor!
