Using your Ultra-Fine tip Sharpie, make a zigzag pattern horizontally. You don’t want it to be overly pattern-y. Might sound silly but I tried thinking of an electrocardiogram pattern from when a doctor is looking at your heartbeat.
Follow the ultra-fine pen with your Sally Hansen nail art pen.
Next use your gold metallic Sharpie in between.
Last, take your topcoat and slowly add a layer. The lines will smudge into each other creating the look. Wait for that first topcoat to dry entirely before adding another if desired. You’ll want to wipe off your topcoat brush each time as it will get a little color on it. I used polish remover and a paper towel.
