First! Two coats of OPI's "Teal the Cows Come Home" nail polish.
I was going for blue, not so much turquoise, but my other flaggish blue is way too dark so I used this one. I'm still not sure I made the right choice for patriotism's sake, but for the final product looking good, I certainly did.
I let the teal dry over night. Then I used Scotch tape to cover all but just a triangle at the point of each nail. Before putting each piece of tape on my nail I stuck it on my hand a few times to decrease the stickiness so it wouldn't rip off the existing polish and it would leave a cleaner line.
Once the tape was in place on all ten nails, I painted two coats of Ulta's "Snow White" over the tips where the triangle was showing. I let that dry some and then topped it off with Sephora by OPI's "Be-Claus I Said So."
At this point everything looked like one hot mess. I also was getting worried about time because everything kept taking so long to dry in the 100+ degree humidity and I was supposed to be somewhere. Ideally, I would have waited until everything was completely dry, but after an hour I got impatient and took off the tape and voila! Nail art!
