I wanted to do a festive water marble using gold, red & green.
I used a base of OPI's Alpine Snow, then for the marble colours I had a few options (shown below) but in the end, I used:
Barry M's Gold Foil - 320
Barry M's Spring Green - 290
and Nails inc Aspen
I did different patterns on each hand, my right hand is more bold and blocky - and the most Christmassy!
