Just wipe the brush off on the lip of the bottle, leaving as little polish as possible, and use a light hand as you paint up, getting heavier as you go.
The colors I used were:
Bizerk Turquoise by Funky Fingers. - This was maybe $2.99 and the brand can be found at stores like 5 and Below
The Gold and the Beautiful by Wet n Wild - This was I think $1.99 and can be found any where, I'm sure. Found this one at Walmart.
What do you guys think?
