Well, the panels do look fine on one side, very much do not on the reverse.  I didn't realize they are intended to only be seen from the fronts.
The space for them is between the side of my porch and the driveway, so I guess I'll order another set and set them up back to back so there are "fronts" on both sides.  Double thickness should make them a bit stronger too, a definite plus as they are quite thin.  At double the planned expense they aren't much of a bargain
