Many artists with a basic knowledge of Illustrator think that the only purpose of Symbols is to create designs to be sprayed on with the Symbol Sprayer tool. But Symbols also are the only way to "map" artwork to the surface of a 3D object. So to "paste" a label onto to a wine bottle, it first has to be made in a Symbol. And like most features in Illustrator, there's more than one way to accomplish this. To create a Symbol of your artwork, either select the artwork and drag it into the Symbols palette OR select the artwork and under the flyout menu of the Symbols palette, select New Symbol, name it and click OK.
