Use a base coat. Mine is bought in Netto.
Put on 2 coats of a nail polish in your choice. I chose Max Factor "Angel Nails".
(Nice name for a polish)
Take a hairpin, stretch it so you can use one of the "dots". Then take another nail polish and dot it on with the hairpin. I chose a red Depend one.
It's really Christmassy I think :-)
I hope you liked it, it's very simple, but maybe You can get inspired.
