Okay, I completely forgot to take pics as I went. If you would like photos, please tell me, and I will add some.
After your base coat, and a coat of tan polish, make like a block of white vertically, using a nail art brush/striper. You can also use a smaller dotting tool, or whatever would make lines.
And make another white block going across your nail.
Then with a black striper/nail art brush make thin lines on either side of your white. Then a line in the middle.
Then make the same three lines on the white block going across the nail.
Then, using red polish, make a line across the top part of your nail. Then a vertical line, as shown.
Then clean up with some nail polish remover and a small brush or q-tip. Then topcoat, and you're done!
Hope your nails turn out great! Tell me what kind of guides you'd like and I'll work on it.
