Supplies first. I gathered a few blue and green polishes from the stash and lined them up as so on a piece of paper. I picked the two biggest dotting tools that I bought a while back and had a paper towel to wipe the dotting tool during the process.
I decided to try it on one nail first and see how I got on, so if it turned out rubbish, I wouldn't have wasted lots o' time. I put a coat of Mermaid to Order from Sephora by OPI on my middle finger. I don't know why I started with the middle finger now that I think of it.
After Mermaid to Order was dry, I unscrewed the lids to the rest of the polishes and left them sitting loose in the bottle, ready for easy access. I placed a little blob of each of the polishes on the white paper and got dotting. Starting at the tip of the nail, I dotted random blobs of the different polishes in a line. I worked down towards the base of the nail, trying to overlap each layer a bit to make the scales. I tried not to have too many blobs of the same colour too close to each other.
Of course, once the first finger was done, I was delighted with the result and forgot to paint the rest of my nails with Mermaid to Order. Ah well. For the rest of the fingers, I worked on them all at the same time, doing a line of blobs on each finger and then moving down a layer.
And here are the results! I have mermaid nails! Just call me Ariel. They kind of look like nail stickers don't they? It took about 40 minutes and to be honest I kind of hurried up doing my other hand because the Eurovision was on and I couldn't handle the screeching...
