Keep on reading after the break!
The way I did this was using a kind of watercolour technique, where I mix the polish with pure acetone to thin it out and then lightly paint it on my nails. With this you do have to work really quickly and lightly (which I always forget when I start) because you are using acetone which is obviously nail polish remover, so if you take too long you actually remove your nail polish! Probably would be easier with acrylic paint and water but oh well, I like to make things hard for myself apparently...
Also, if that made no sense, I made a tutorial with these ones (YAY!), plus there are tonnes of pictures to look at (woo!)
I will see you guys next week! Also, get outdoors, its fun! :P
