I don't do Hallowe'en, but I'd seen lots of nails like this recently and wanted to do some too!
I started with 4 purple polishes and made a gradient. I used Barry M Black Currant and Blackberry, Jacava Holbein Place and Barry M Fondant, to take it from an almost-black purple to a pale lilac. I started with a base of Jacava Holbein Place, and then sponged on the gradient.
I really like how this came out, and I wore this on its own for a day, with topcoat to make it glossy.
The cleanup round the cuticles was quite awkward - that Barry M Black Currant again! I still liked this though.
I then tried this matte, just to see what it was like. I like this too!
I then used a Barry M nail art pen to freehand a tree and some gravestones.
I like the contrast of the black against the sort of sunset sky, and the glossy against the matte.
I wish Black Currant wasn't so messy round the edges though!
