U KNOW your going to use lattice.. I would just get a few sections/panels & do a trial & error..
I'm sitting here w/ a lot of ideas.. how about this, how about that.. but its hard to REALLY TELL unless your there moving it around..
WHATEVER U DO, get the PLASTIC lattice..
& keep in mind access.. put a few sets of hinges on a panel..
& PLEASE Post a pic or 5 of the result..
Really good idea Kenny..
