The inspiration for this project came from all the beautiful images on Pinterest of marbled fingernails. We know exactly what will be going into these little bottles, and as it is something rather special, we wanted the decoration on the bottles to be as fabulous as the contents will be!
We used a selection of nail polishes that I didn't mind using up. Commonsense would suggest that a newer nail polish would be thinner, and probably give the best result, but I just hid the ones that I love, and also took away all the quick drying ones, letting the kids choose from the rest. Before we started, we also planned how we would dry the bottles, as they clearly wouldn't be safe upended on their necks. Our solution was pencils stuck into an old, slightly manky-looking (sorry about that, but I knew it would come in useful one day!) floristry oasis, anchored into a pot.
We used warm tap water, and gently dropped the polish on to its surface. We found that if you just tipped it in, it all sank to the bottom, so we let it pour from the bottle onto the brush, held just above the water, and that worked pretty well. Once we had added our colours, we used a cocktail stick to mix them up to get a marbled effect. I'd advise using a container that you don't mind ruining, I didn't even bother trying to clean ours, instead have just put it aside for next time.
We then popped the sides of our bottles into the water and turned them gently. The nail polish grips the glass immediately, and clings on, so you get pretty much all the nail polish from the surface of the water attached straight away. This would mean that with bigger objects, you would have to go through the process a few times to cover it all.
We then popped our bottles on the pencils and left them to dry. We like how all ours turned out, but it would be easy enough to remove any smudges, or indeed the whole thing with nail polish remover if you weren't happy with your results.
This technique turned out to be far easier than I expected, we will be on the look out for bargain nail polishes from now on, and fancy trying to decorate some glass tealight holders next - we think the effect would be stunning with a lit candle inside!
