As i’m writing this i’m waiting for the base colour to dry on my right hand (the colour is China Glaze Something Sweet), and as you can see i’m doing water marbeling! this is way harder than i thought 
first off i could find a toothpick, so i had to use a crochet needle, which is a bit too big i think.
It looks ok so far though! i’m really pleased with my thumb, index and pinky finger!
oh wow, it looks really good!
i’ve always wanted to try water marbling but it’s always such a mess that I don’t even bother
