We just spent our first Christmas in the RV. We decorated much like we would at home, but on a smaller scale. Here is the best solution for hanging stockings that I could come up with in our RV.
My camper has fabric covered cornices above most of the windows. I knew I wanted my stockings to hang from the cornice for a couple of reasons. First, it was the only place that really made sense when I looked around. Secondly, it was directly behind our Christmas tree which I thought looked good. I tried to sit my stocking hangers from home on top of them, but they wouldn’t fit.
So, I pinned the stockings to the top of the cornice with large safety pins. It looked great! The pins were hidden, and the stockings hung beautifully. I have included several pictures below.
