As soon as I was PHD's Challenge this week for a grayscale a water marble popped into my head. Not soon after I knew I wanted to use a hot pink. The only one in my collection is Sinful Colors Fusion Neon. I did a BC and then one coat of Sinful Snow Me White. I've been using the tiny dixie cups for my water marbling, and while they work well there's not a lot of design area to work with in the cup. I dug through the cupboard and found a Malibu Rum wide shot type plastic glass that worked soo much better! I used Savvy in Ebony Black, Sally Hansen Xtreme Nails in Gunmetal and Sinful Snow Me White for the marble.
This is by far the best water marble result I've gotten - hooray! I then decided to do a free hand chevron tip with the Fusion Neon.
