As the Swede I am, I really missed a proper winter in the December London. Solution? Create winter on your nails. I found the snowman design online, but it then had a silver background. I used silver for one hand, but think that dark blue turned out better. In order to make the snow I used mainly white but then added a few flakes where I'd mixed silver and white for a softer touch.
Approaching end of term, and hence a number of Christmas events, I started elaborating with holiday designs. I went through two - one a bit more subtle than the other. Picking a favourite is up to you!
