In the fake campfire shown here, real wood is used to help create a realistic-looking fake fire. For best results, use varying thicknesses of wood logs and twigs. If you only use large logs in your fire pit, your fire make look less realistic. A mixture of different types of wood looks more like a campfire and, more importantly, the smaller pieces of wood help hide the orange lights below. Varying sizes of logs and twigs filter the light through just like a real campfire that's burning down to embers.
