Hi Tracey, thanks for the picture comment.
I painted on the base colour as usual (2 coats) and then put a slightly thicker, but still thin, coat of my second colour on. Before curing, I used a dotting tool and dotted drips of D.Solve/Harmony Gel Cleanser on to that uncured coat which created this effect. Cure and finish off with Top Coat as usual. Hope that explains it. x
