Okay, so to get started, you're going to gather the things you need:
. Various nail polishes &
. Your unwanted guitar picks
So, before you start to paint your pick, you should draw your rough design on a piece of paper, i just traced around my pick and drew on that :)
This is the pick I'm going to use
So to start i used a white polish and painted a base coat. (I needed 2 layers to cover mine.)
Then, I used a red polish to paint the little heart...
Then, using a black polish i painted on the character and after that dried i coated it with a clear polish, let that dry and... you're done!!
