neon polka dot french 2 My take on a French mani for the season…the neon polka dot French. I began by painting my nails with a solid white polish – Sally Hansen xTreme Wear in White On. I then rounded up five of the closest shades to neon I have in my collection. Make small dots across the tip of your nail, changing colors after you complete each nail. Voila! A neon dotted French.
