HI Darlene, Here are all kinds of great idea on what to do with a porch wall. Maybe some will spark an idea ;) Have fun! https://www.hometalk.com/search/posts?filter=decorate%20porch%20wall
We have a screened in porch on our house and I have decorated the one big blank wall many ways over the years. A quilt, china, shells etc. Right now we have a mirror on our porch wall. It is pretty heavy so may stay there a while. You can do whatever suits your taste and budget! And climate where you live.
This is the porch if the picture goes through.
The porch is done but not decorated. Have good ideas except for the camper wall.
