Now I can't really take credit for the idea, as I was inspired by @rendxnails on Instagram, but I did paint it myself freehand so that's something! Sadly mine are not as neat as hers but I'm still pleased with it, the neon keeps catching my eye and I've been complemented on them quite a bit.
To do this nail art I used a small nail brush, and painted a line on each nail in red, then coral, then yellow/green and so on. I'm used to doing advanced stamping where most of the reason the nail art takes so long it all the drying time, so it did feel odd to spend nearly an hour solidly painting my nails! When I got half way through I was having second thoughts about whether it was a good idea! As I went through each colour I think I improved my painting technique slightly. I have to say it's lucky they are such good strong one coat colours, as I didn't fancy doing another coat!
