Use these simple step-by-step directions to construct a garden trellis
Rip-cut lattice slats to 3⁄4 inch wide. Cut five verticals to the height of the frame and eight horizontals to the frame’s width. Lay the verticals on a flat surface and experiment until you achieve a consistent spacing; cut a scrap board to use as a spacer. Do the same for the horizontals. Check the lattice for square, and fasten each joint by applying a dab of glue and driving a 1¼-inch finish nail or staple.
