I need some help on ideas for decorating my camping tent?

We camp a lot in a big group. This time around we are having a curb appeal contest. We will be judged on the creativity of decorating our tents making them feel like home and we have to bring the stuff with us. We can not use things from the camp site. I just need some ideas. Keep in mind I my most available power source is batteries and propane.

Definitely bring a couple of cute dishtowels to hang up as curtains in the mesh "window", if your tent has one. (You can "sell" the idea that they are curtains by tying them back with a sash.) Also, look for the plastic lattice segments that people put around flower beds; it will look like a mini picket fence. While you’re at it, a few potted plants and flowers could go in your "yard". Make a "deck" with a few wooden boards (or vinyl imitation boards) and set out a couple of lawn chairs with a plastic table. A couple of fancy-looking drinks with paper umbrellas could brighten that table. A set of horseshoes or bocce balls will make the "lawn" look lived-in.

All of that is relatively cheap, not too heavy or bulky, and won’t need any juice from your batteries. If you want to use something battery-powered, I would get one of those camp lamps that looks like a miniature table lamp, complete with lampshade. Put it on a table inside the tent, where it can be seen through the mesh window.
