Some easy-to-make cartoon costumes are Dora from "Dora the Explorer," Finn from "Adventure Time," Minnie Mouse, Miss Frizzle from "The Magic School Bus" and any of the turtles from "Teenage Mutant Ninja Turtles." Parents and kids can easily make these costumes with clothing and materials found around the house.
A Dora costume requires a pair of orange shorts, a pink t-shirt, yellow socks and white sneakers. A purple backpack is also necessary, and construction paper can be used to make the face. Someone who wants to dress as Finn from "Adventure Time" needs a blue t-shirt, blue shorts and white knee socks. Finn also wears a white cap with long ears, which can be made with a pair of socks. His sword can be purchased from a toy store and painted pink. All that's needed for a Minnie Mouse costume is a red dress, a headband with ears made from black felt and makeup to color the nose and whiskers. Make a Miss Frizzle costume by wearing a blue dress over a white collared shirt. Make planets from construction paper, and pin or glue them all over the dress. For "Teenage Mutant Ninja Turtles" costumes, get green shorts and a t-shirt. The shell can be made from an aluminum baking pan painted green.
