I started off with a clear base and I added a couple of scoops or some holographic glitter that I got at a nail supply shop. I followed with a generous scoop of Spectra Flair and ended it with some black and voila! I didn't want it too dark as I already have revvvolution and I wasn't trying to dupe it so it's not quite a charcoal holo. I also made this trying to answer the question in my head of, "What happens when you mix linear and scattered holo?".
Now for the picture bomb...
The following are under a lamp, I was trying to figure out the angles to see what would show
off the holo the best, the last picture was purposely blurred to show the holo.
I ended up discovering that it photographed the holo best away from direct light....
Soooooo, what do you think?
