If you saw my previous post on the Illamasqua Nail Quills you will see where I got my inspiration from to try and create a similar effect for much cheaper - as the Illamasqua Nail Quills cost £35 for a set of two!
I used a couple of coats of OPI 'It's totally not forth it' which is a shimmery silver just on the tip of my thumb nails. I painted the rest of my nails a dark smokey grey almost black OPI 'Suzi Skis in the Pyrenees', then applied the dark around the triangle shape I created with the silver on the nail tips.
My nails are quite shorten and neat at the moment, so I created a triangle shape rather than the diamond shape on the Nail Quills. If you have nail extensions you could of course create the diamond on the tips.
What do you think? Let me know if you attempt to re-create the Nail Quills :)
