The most important thing about making your cabin feel cozy is lighting. Candles are a great way to set the mood, but flashlights can be used for light as well as for finding things around your campground at night. If you're camping away from electricity, it may be difficult to find candles that won't blow out easily in the wind, so consider bringing battery-powered candles instead. Another option is bringing along an oil lamp or other portable source of light that doesn't need oxygen to burn.
