I started off with a neon orange polish and let dry. Then I layered one coat of Sinful Colors Black On Black, followed by a coat of Sinful Colors Smokin'. I let those dry for a few minutes and then applied one coat of the matte top coat from Butter London.
After a few minutes, I used my index finger on my right hand and pressed the polish and tried to slide it across the nail to create the ridges and bring the orange out. I did go back in with a nail art brush and add in some more orange if it pushed it off to show the bare nail. I also added a bit of yellow in places like you see with lava. No top coat after this step, since the texture is what this week is all about!
