I need some ideas on how I should decorate this metal barn for our reception. We were looking for a barn for the reception, but were hoping to find a wooden one. Unfortunately, we weren't able to find one that wasn't being used, but a friend said that he would lend us his. It is very large (60x60) so space will definitely not be an issue. I posted the picture of the truck so that you could see just how large the inside was and so that you could see what the walls/ceiling look like. It will be completely cleaned out for the reception. We're going for a more country, rustic look. As you can see in the picture, there is a bathroom built into the front corner of the barn which is decorated country/rustic. I've considered using PVC pipe and tulle to cover the walls, but with such a large space, I'm fearing it will be quite costly. I've found so many ideas/threads for wooden barns but none for metal barns. PLEASE HELP! Any ideas will help.

I cant seem to find the video now, but there was one on theknot.com that a couple had made by a videograher and their reception was in a metal barn and it was beautiful! Im sorry I cant be of more help, but do think about how the noise will travel with it being metal if you have a DJ!

@uwf_cole23: that's a good point. I didn't even think about how it would sound in there. Thanks for the heads up!
