The best things about doing galaxy nails is nothing has to be perfect. Its how much you want of each color & where you want the colors. To begin I painted a coat of black nail polish. After that dried I painted some teal/green (Sinful Colors Rise and Shine) in random places as well as some maroon (Essie Show Stopper). (These don’t have to be your color choices. If you look online some people use colors such as purples & pinks in their galaxy nails.) At the end I painted on some old Wet & Wild clear gold sparkle nail polish I found in my house. You need a polish that is clear & has sparkles in it so you can see the other colors under it.
Really easy & cool all at the same time.
Good Luck XXo
