I think the combination of the peach and green shades work really well together in this design.
I started by painting all nails in 2 coats of my base colour. I wanted each nail to be slightly different and so this was whatever colour was closest to the base of the nail.
I then added on my second colour to each nail. I placed it so that I could split each nail into different stripes of colour. Again I attempted to randomise the order of the colours.
Once this was dry I repeated the same with the 3rd colour, so that each nail was left with 3 different stripes of colour. On the darker green/tourquize shade, I went over it with a multi glitter top coat as I wanted each stripe to have a different finish to it.
Lastly, I covered over the lines where the different colours met with a gold holographic striping tape. This helps to make everything look a lot neater.
