I'm very happy with my results this time!
The colors are:
Blue- China Glaze First Mate
Red- Illamasqua Ruthless
White- Wet N Wild White Creme
The video I used for inspiration is posted below. I was much more patient this time in waiting for my polish to get tacky and that helped me to get the look I was going for. The longer you wait, the thinner the strings will be when you lift your dotting tool out of the polish (you could try using a bobby pin or a toothpick if you don't have a dotting tool).
I put a few drops of blue and red on a plastic bag and waited a few minutes for them to thicken up. If you don't want to wait, let the drops of color start to thicken up while you paint your nails. By the time you finish painting the drops should be thick enough for you to be able to start making strings!
