Used red, white and blue nail polish on my four daughters toes (yes, that makes 40 toes!). Painted the big toenail blue, then all the other toenails red for the holiday.
After painting the other nails red the big toe was now dry. I placed a small dollop of white nail polish on a napkin and then used a match to dip the polish and then 'dot' the big toe, repeat as much as you want
Hint: for babies or toddlers who can't hold still, wait for them to fall asleep to paint their nails
