This is for a lovely reader who emailed me to ask how to prevent/get rid of air-bubbles when water marbling. Well, there's no easy one-way-fits-all answer to this, but there are some small habits that I've adopted that work most of the time.
1. Find the right temperature for you water, this is tricky! Play around for a little while, you'll find it. Usually, it's near room temperature, I fill my cup up and leave it out for a little while before starting.
2. Find the perfect polishes. Some don't spread, some create air bubbles, some just aren't pigmented enough. It's not really a brand thing, it's really individual. I've had luck with a lot of Orlys but some SH Xtreme Wears work for me (Mellow Yellow) and some don't (Green With Envy). This is another field that you just really have to play around with.
3. Dip your nail straight in, clear away the residual polish then draw your nail straight out. Angles tend to cause bubbles for me.
4. This is my secret, really what I do to avoid bubbles: I blow on the nail right after taking it out. Please note, this isn't the kind of 'ooh I need this dry quick' blowing, I just give it one sharp breath of air to blow away all of the water sitting on the nail bed. It works for the bigger bubbles.
5. For smaller bubbles on less detailed designs I wait until the nail is 95% dry then I smush the design a little with the pad of my index finger. Once I've done that, I take a little bit of polish the color of the (now flat) bubble and fill it in. This looks very realistic once the top coat has been applied.
6. I breathe in and get over it. This isn't meant to be perfect and nobody but you will notice the smaller bubbles. I promise. It's okay, your design looks awesome! Rock it with confidence.
Now, this is my marble. I took one of the CC French collection light pinks (name doesn't really matter, there were like 3 of them), SH Mellow Yellow (which was my base color), and CC Take Me to Your Chateau and marbled them. The pink added just a hint of peach to the nail and the blue looked awesome. I had a bit of bubbling, but I used my own tips and the mani looks great.
