Do NOT apply 2 coats of a base colour, be impatient, apply french manicure strips, add white polish on tips and expect it to NOT come out like this! Notice the ripped up base coat?
Instead, apply French Polish Guide Strips (I used the ones from Nailene) to either bare nails or on top of 1 thin coat of clear base coat. Give ample time to dry, then apply 1-2 THIN layers of white (or coloured) polish to tips. Wait till dry to peel strips off then apply your nude or neutral colour and top coat.
Here are the 3 polishes I used. Zoya's Snow White, OPI's Got A Date To-Knight and a Top Coat Plus from Nicole by OPI.
The final result after doing it right and taking my time......
Not quite salon quality, but for this self polishing, french manicuring newb... not half bad!!
