Marbling Fail

I have been meaning to try marbling for ages and was reminded by Marina a few days ago. My first attempt didn’t go very well. I ended up with lumps and bumps everywhere and more of a clumping than marbling effect. I think it’s because I dunked my fingers in, then pulled them back out without remving the excess which then also stuck to my nail.
I used:
L’Oreal LacquiResist – Bebe Blue
and two old Collection 2000 polishes in a red and pink colour.
then a top coat of NYC

As you can see, there’s much room for improvement so any advice is welcomed!
