Purchase Vertical Lattice, not diagonal ?

Check your local lumber yards. Big box stores will not have anything, though they may, but I highly doubt it.

MOST is made by the person building the screens, or whatever, by tacking strips together with brads and glue where needed.

Your best bet beyond doing it yourself would be a true lumber yard.

I dont know why but I cant stand the sight of lattice, the kind you dont want. Like Scott says…......easy to build your own horizontal/vertical lattice.
