Have you found your effect?

If you can't get to a minx salon, I would say this would be the next best thing!  They should definitely come out with more prints but the ones they have out on the market are really pretty... Check them out at your local beauty store or clk on this link Sally Hansen Salon Effects      
It's also a lot more affordable and a total DIY (do it yourself!) There's also a video when you get to the link that will walk you threw it, if your a newbie.
