I really like grey polish at the moment, so Essence I'm the Boss is right up my alley. It's a medium to dark grey polish with sparse-ish silver glitter. It's really pretty and was opaque in two easy coats. To make it Halloween-y I stamped spider webs using a Bundle Monster plate and Barry M Silver Foil. I'm still working on my stamping skills so the image didn't transfer perfectly, but I think it adds to the effect rather than detracting from it (that's my story and I'm sticking to it). Finally, I used Nails Inc Black Taxi and some striping tape to make black French tips.
I went to Waitrose today and they had a section dedicated to Halloween food and decorations. I bought a bunch of it. Apparently if something is coloured orange and black at this time of year, I will buy it. All of it. People don't really trick or treat where I live but I bought some spooky chocolate just in case - and if we don't get anyone, oh well, more for me!
