I've got hooked to the Olympics!!! and above all to the gorgeous nails of the competitors, especially the swimmers.
The U.S.A gold medal winner, Missy Franklin with patriotic nail art, one hand in red with the American flag and the other one is the same only in blue.
The 400 m swimmer, Aimee Willmott, U.K had the Olympic symbol on her thumbs and red on the rest.
Here is the DIY for your Olympic nails in 5 steps:
Step 1: Apply 2 coats of white
Step 2: Take a piece of sellotape and a toothpick. Tape it on a flat surface
Step 3: Drip a drop of blue on the tape
Step 4: with the dipped toothpick draw a circle
Step 5: keep on 4 more times.
If you don't have green you could combine yellow and blue together
