Lattice is inexpensive and demands no special expertise to build -- you can install it with only simple hand tools and an electric drill/driver.
The term latticework refers to any decorative pattern made with narrow, thin strips of wood. Latticework designed to give privacy has 1-1/2 inch openings; with garden-spaced lattice, the openings are 3 inches.
Prefab Vs. Homemade
Most lumberyards and home centers sell 4 x 8-foot prefabricated lattice panels for a cost that often is less than that for the lath alone. These panels are easy to install because the cutting and nailing already has been done. Inspect prefab latticework carefully before you buy, however. Cheaper varieties often are made with lath much thinner than that sold in individual pieces, and the staples holding cheap lattice together may be thin and dislodge easily. For this project, we used a prefab panel.
