I used my small silver square studs and was trying to come up with a good colour combo, I'm not really a big fan of bright colours but I didn't want to to go too dark all over either. I finally decided I wanted a light grey but the only grey I had is quite dark, it's 17 smoke signal. I decided to make my own by adding some of the smoke signal to white. For the other side I used 17 midnight sapphire. I used some clear polish where the colours meet and while it was still wet and tacky placed the studs. They weren't as meticulously straight as I would like but I didn't want to risk smudging the polish to fiddle with them too much. I then finished with top coat.
I really like this mani and quite like the feel of the studs, I thought they would get in the way or get caught in clothes but so far so good. :)
