Pinterest Fail - Marbled Mugs Using Nail Polish

I'm a little bit obsessed with upcycling, re-purposing and re-imagining my beauty stash.  So when our intern Nina showed us a video of creating beautiful marbled mugs using nail polish I was keen as a bean to give it a go.

I scoured Pinterest and yeah, it looked pretty easy.  Take a bowl of warm water, pour in nail polish, stir, dip mug in, voila.  Look at this example from Pinterest:

And this one, from a KIDS page, it must be easy right?

Yeah.  Easy.  

I mean LOOK AT IT.  It's less marbling, more rainbow bird poop.

I called in The Husband for the next few attempts, because he's arty and I clearly struggle with kiddie crafts.

Apparently the technique is - hope the nail polish pours in to an ok pattern, swirl it with a toothpick like you know what you're doing and dip the mug with conviction and swagger.  While working quickly.  

The attempts did get better, but yeah, I don't think these will be sellers at the local boutique!

Have you tried nail polish marbling?  Was your attempt better than this?
