Begin by cutting off a 10-in. length of the board and setting it aside. Rip the remaining 38-in. board to 6 in. wide and cut five evenly spaced saw kerfs 5/8 in. deep along one face. Crosscut the slotted board into four 9-in. pieces and glue them into a block, being careful not to slop glue into the saw kerfs (you can clean them out with a knife before the glue dries). Saw a 15-degree angle on one end and screw the plywood piece under the angled end of the block.
Aside from the privacy it offers, a latticework porch trellis is a perfect way to add major curb appeal to your home for $100 or less. The trellis shown here is made of cedar, but any decay-resistant wood like redwood, cypress or treated pine would also be a good option. Constructed with lap joints for a flat surface and an oval cutout for elegance, it’s a far upgrade from traditional premade garden lattice. As long as you have experience working a router, this project’s complexity lies mostly in the time it takes to cut and assemble. Get the instructions complete with detailed illustrations here.
