I love doing my nails like this for weddings and work. I rarely go get manicures now because doing it myself is so much easier and cheaper. It's even easier to do on your toes because you don't have to worry about working on your dominant hand. One thing I forgot to mention on the tutorial is that you could also add a base coat after you clean off the white tips (right before you put your top coat). This will help the top coat from staying on better.
I use Orly French White for the white, and Seche Vite for the top coat.
