I'm posting this today because after trying the system out, I got a massive headache and just couldn't be bothered to stay on the computer much!
I mucked about with it for a while, trying to figure out which polishes I could use - turns out, not many! I first tried out some of my No7 collection but even though they are 'pigment rich', they didn't show up at all. I then tried out Barry M, which generally worked better. The best ones were the silver and gold nail effects.
I have ordered Sally Hansen Xtreme Wear White On & Black Out, so hopefully they'll work better than my black and white!
This is my best effort from yesterday and it is pretty messy but I really wasn't bothered much about it because I was just trying out techniques.
This is what I used:
Base colour: Barry M Vivid Purple
Stamping colour: Barry M Instant Nail Effects Silver Foil
Stamping plate: BM-208 for both stampers.
The ring finger is done from the same plate as the others but is the inverted one.
It very much resembles crackle nail polish, but it's a lot neater and obviously isn't bumpy. I'm looking forward to trying out some of the other designs I have, and seeing if there are any other polishes i have that also work.
