Wooooo...I have successfully done a water marble! I first tried a water marble about 2 years ago when I was just getting obsessed with nails... it did not go well. I couldn't get the polish to anchor to the sides of my glass so I couldn't draw any nice design in the polish and the polish I had was, to put it politely, crap! So now I have better products I thought I would give it a second shot and hallelujah it worked!
