Hello Lindalou64. You can use your nail polish like you would use paint. You can use a pattern or free lance a design on your wall plates. You can include kids on a project like this. Good luck Lindalou64.

You can put nail polish in water and dip white plates to make marbleized feature.

Here you go, instead of a vase, use your plates:
