I actually did this a couple weeks ago for UCF's homecoming week, as I work for UCF. The mascot is the knight, and our colors are black and gold, so I thought it was fitting! I was just bogged down and unable to post when it was actually homecoming week though. You might remember that I did something similar when I graduated from UCF though.
I started off by painting my nails with two coats of Zoya Raven, and then topped that with one generous coat of the 18k gold topcoat. The flakes are a little sparse, but I think that's okay since they're so large. I didn't want to go too wild with it since the clear base adds up, so I left it at one coat.
I love how it turned out though! It almost looks like marble or some sort of stone. The flakes all laid completely flat and I had no issue with them. I didn't have to try and get a bunch of flakes on each nail - I got quite a few on every nail.
It actually started to dry a tad matte. Not completely, but the clear base started to look a little foggy. So I applied one coat of Seche Vite on top to make it glossy again, and I'm glad I did! My nails were so shiny and I just could not stop looking at them. I also love how Raven isn't just black, but also has some subtle shimmer to it as well. This is another combination I'll have to try in the future!
