Nail polish is very simple to use and tons of colors to choose from. Very small investment also. I started out using it and at one time owned probably 20+ colors. My daughter would come ask me if she could use MY finger nail polish because i had better colors than she did. Powder painting is very easy to do as others have said. Once i got started with powder, gave all my polish colors to my daughter and never looked back. I still have a bottle of clear polish (Hard as Nails) around at all times though for thread necks.
