I used the dark blue around the crease of my eye and winged out, then I patted both the glittery aqua and purple shades in the centre. I'm obsessed with the shimmery, silvery, iridescent finish of Ultraviolet. I wanted to layer it over everything. I was also super impressed with Sunburst, the glitter gold I applied to my inner corners. It brightened up my entire face.
I figured these shimmer shades would work well as highlighters, too, so I tried to dust on Milky Way (ivory with iridescent glitter) on my cheekbones. Sadly, I felt that the fallout was too much and getting all over my face instead of where I wanted. It's not ideal if you're using a fan brush, so maybe stick to an eye shadow blending brush if you plan to make these eye shadows do double duty.
