Step 1: Polish with your background color. I used Color Club Gossip Column.
Step 2: Just using the polish brush, add your pumpkin. I used Julep Parker, two coats.
Step 3: Using a fine striping brush, add your darker orange accent lines. Round them to follow the contours of your pumpkin's shape. I used Jordana Orangesicle.
Step 4: Add your stem with a small detail brush. Overlap it a tiny bit on to your pumpkin and make it slant to one side so it looks more organic. I used Sinful Color Nirvana for my stem.
Step 5: Using a small, pointed detail brush, outline your jack-o-lantern's face with black. I did a classic, happy face, but you can do whatever face you'd like to try.
Step 6: Fill in your face with black. I used China Glaze Liquid Leather.
Step 7: Add a yellow highlight to make your pumpkin glow. I used Sinful Colors Pull Over.
Step 8: Make your sky twinkle by adding some tiny stars. I used Julep Brigitte, the lightly brushed some thinned NYX Ink over the top of them to soften up the stark white.
Step 9: Finish it off with a top coat!
Now repeat on all your nails, or you could just do an accent nail or two. Now you have a super cute Halloween mani to show off!
