You all have inspired me to do this for our trip, for myself and dd11.
I tried today, by doing a base coat of red, white polka dots all over, then a black mickey head on the big toe. They look good close up. However, from normal veiwing distance (hoping people won't be too close too my feet!) it just looks like something is really wrong with my big toe nail. I may need to stick with white and red.
All of your pics are really cute, though!
