I used saran wrap (cling film) to dab on some Revlon Gold Coin on to the Guava. Most tutorials that I have seen on this technique paint the second colour on to the nail when the base is dry and then dab it with the cling film. I have tried that earlier and I found that I ended up dabbing on too much or too little and wasn't happy with the result. So I tried it a little differently this time.
I started with a base of Barry M Guava. Then I used a scrunched up piece of cling film painted with some of the gold nail polish and dabbed it very lightly on to my nails. If there was too much gold in some spot, I went back and touched it up a little with some blue polish on the cling film.
