Cut a 4-by-8-foot wooden fence panel in half so you have two 4-foot-square pieces.
Paint the wooden pieces with exterior primer and allow to dry. Apply two coats of waterproof sealant to protect your accent fence from weather damage.
Determine where the corner of your accent fence will be and use a sledgehammer to pound a fence post holder into that spot. Slide a fence post into the holder and secure it by tightening the base screws. Position the remaining post holders so that they are 4 feet from and at a 90-degree angle to the corner post. Install the end posts in the same manner as the corner post.
Secure a fence panel to two posts with deck screws and furring strip braces. Repeat for the other side and your corner accent fence is complete.
