This is a customer submitted photo showing a 600lb mesh on top with a hex mesh base. A smaller opening size base (1") can help exclude smaller animals. Both materials aren't visible from a distance, this is a fairly close up picture. Most customers that utilize a hex mesh base would run deer fencing material at 7' and simply overlap the hex mesh on top of the deer fencing material - in this picture, there is only a few squares of overlap. It tends to blend together better and look a bit nicer with full overlap (your square poly mesh runs all the way to the ground and the base is installed over it).
These three pictures are of full size poly mesh (7.5' tall) with 1" opening black hex mesh overlapping it. The contrast blends together well with complete overlap, you can barely tell there is also different mesh on the bottom.
