I created these festive nails a couple of days ago. I went for pastel colours as I was at work and pastel is less in-your-face. The three main colours (pink, purple and green) are Nail Geek polishes that I'd been sent to review (see previous posts for reviews!).
I did three coats of pink/purple on alternate fingers and left them to dry. I then used straight vinyls (you could use striping tape, or normal tape) to section off triangles on each nail. I filled in each with green, and added dots of gold and silver polish with a dotting tool to finish them off!
