Ok so this may look familiar. I have used this glitter before, it's just that it's so sparkly, I can't help it. Like, the most sparkly. Sure, it's a pain because you have to be careful you don't get two pieces stuck together and the glitter won't sit flat flat but LOOK AT THE SPARKLIES. I even made a time-lapse video of how to do it! It's like, if I say I'll do something a thousand times, I might actually do it! Also, sorry about the lobster fingers, sparklies > normal skin tone.
I wanted a really sparkly base to match the glitter so I started off here with two coats of Sephora Formula X Freaky Like Freud, a ridiculously sparkly micro-glitter polish. Then, I applied my usual thick coat of top coat down the middle of my nail, laid down my first column of glitter then laid out each side. The good thing about using matching base colours is that you don't really have to bother about cutting your glitter to fit. Looks better without it for once. Two coats of Seche Vite and you're done. Just make sure you press all the glitter down as you go.
The Verdict: THIS CAME OUT SO SPARKLY I CAN'T EVEN WORDS GOOD. Like, SO SPARKLY. LIKE, SO SPARKLY. I love you, glitter, for always.
