when i do child pamper parties, i pick about 6 polishes in bright colours that i put on the table and tell them to pick a colour, that way they have a limited choice, if you give them a wide range to choose from you will be there forever waiting for them to choose. then i apply jus one coat cos it drys quick and do flwers with a dotting tool or flicks. i normally jus offer black or white for the art.
