I honestly don't know why but I am having some serious issues with the Needle Marble technique. It should be real simple and I see so many amazing manis made by this technique, but for some reason I just can't get it right. So I took me a free evening and decided to give this method a try. It did take me quite a while until I was fairly happy with all my nails, but I did it!
Then I applied, one nail at the time, 4 lines of polish using Orly Instant Artist stripers in (from tip of the nail and down) True Blue, Chocolate, True Blue and Blue J, and with a long needle I dragged the polish is quick lines from the tip towards my nail beds. My index nail turned out best and I had to redo at least 2 nails more then once until I was happy with the results, but I am really liking this effect and I will have to practice it some more!
