Hi, I need some advice. I'm trying to do a french polish where I have contrasting glitter tips over 2layers of Shellac polish. How do you get a perfect smile line with the glitter and how do you prevent the rest of the nail plate being contaminated with litte bits of glitter? Help??!! Whenever I do it theres always tge odd bit of glitter gets onto the rest of the nail & I can't get it off! Grrrr xxx
