The first step in decorating pine cones for Christmas is to gather a variety of different supplies. You will need different colors of paint, glitter, glue, and other decorations such as buttons or tiny ornaments. Once you have all your supplies ready, the next step is to start painting the pine cones in whatever colors you desire. You can use multiple colors to create a unique design or just one color for a more simple look. After the paint is dry, you can then add glitter to the pine cones to give them a sparkling effect.
