I used a base of Barry M Cotton, and then marbled using Pink Punch, Rose Hip and Dragon. I then covered up the worst of the smudges with a topcoat of China Glaze Travel in Colour for the shimmer. Then I used Barry M Matte Topcoat for the matte effect.
This reminds me of ice cream!
Even my right hand came out quite well! (Although I found it harder to tidy the edges!)
I'm a total convert to water marbling, especially now I know about using liquid latex to keep the skin clean for it - see my post here.
