I've had this manicure in my 'ideas' folder for aaages, and I finally got round to trying it! I pinched the idea from Top Coat It - you should check her blog out, there's some fantastic nail art on there.
CRABS! And sparkly disco crabs, at that.
I used China Glaze Kalahari Kiss (the colour isn't very accurate here!) then I freehanded on the half moons and claws using Barry M Bright Red and Red Glitter, then added eyes with a dotting tool and Barry M Matt White and Black.
Aren't they adorable? So glad I finally got round to trying this! And yes, the fat claw on my thumb crab is totally intentional...
