Well, I've gone and royally messed up my camera settings...that'll teach me to mess around when I have no idea what I'm doing. So, apologies for the slightly odd looking pictures. Is it me or do they look very washed out and my hands look extra wrinkly?! Me and my camera are definitely not friends at the moment.
Anyway, I did this accent nail using striping tape, and then carefully painting between the tape with a small nail art brush. I used Models Own Beth's Blue, Barry M Lemon Ice Cream and Barry M Berry Ice Cream. It reminds me of seaside rock!
