I'm not overly into makeup and nail polish, I only ever have my toenails painted, but there are a lot of creative ideas to be done with nails. If only mine didn't break all the time! I have tried the marbling trick, which was time consuming and a little fiddly, but came out well after a few goes. I did it for Christmas in Christmas colours following a few tutorials from the net. Some of these other ideas seem fiddly and time consuming too but if they worked would become artworks in themselves. I'll have to give some of these a go..
