I'm really bad at asking people for suggestions for how I should do my nails, then completely disregarding the excellent suggestions and doing something I saw on Tumblr. I saw this awesome stupendous creation a few days ago and just had to do it. Triangles!
I wasn't quite in the mood to make the base colours too complication for this one so I thought I'd just sponge on some random colours. To start, I did the usual two coats of OPI My Boyfriend Scales Walls. Once that was dry I cut myself a small piece of makeup sponge and just splotched on Urban Outfitters Hottub, Rango and Blue Velvet. Once it and the coat of Seche Vite was dry, I cut a long strip of striping tape and went to work. I found it was easiest to lay the horizontal stripes first, then each of the diagonal lines. I did all the taping at once and when done, applied a thick coat of the very excellent almost-holo A England Bridal Veil. I didn't want flat black and I love this polish as it's a one-coater and has great texture. One more coat of Seche Vite and I was done.
The Verdict: This actually came out better than I expected. I wasn't careful with how I sponged on my base colours - I just kept putting it on til the colours looked blended without going brown. And my triangles came out really even, and that never happens. So yay, neon triangles!
