Pinterest is an online site where users create boards to organize and share ideas, recipes, projects and more by pinning images and links. It allows people to plan weddings by finding decoration, invitation and reception ideas, save recipes sorted into categories like dinner, dessert and drinks, explore their personal style, get crafting ideas for gifts, jewelry and recyclable projects, and teachers can find classroom decoration, science experiment, and lesson plan ideas. Pinterest is organized by user-created categories and boards where people pin whatever topics interest them.
