To make a Christmas cone tree, you will need the following supplies: cardboard cones, scissors, glue, glitter, ribbon, and small ornaments. Start by cutting the cardboard cones to your desired size and shape. Then, use the glue to attach the cones together, forming a tree shape. Once the cones are attached, sprinkle glitter on the tree to add some sparkle. Next, tie a ribbon around the base of the tree and hang small ornaments from the ribbon. Finally, place the tree in a prominent place in your home and enjoy the festive atmosphere.
