Caution: This step involves hitting nails with a hammer in close proximity to your fingers. Work gloves are recommended if you are unfamiliar with using a hammer.

Hold a wood nail approximately 1 inch from the side of the picket.

You may place the first nail 1 inch away from either the left or right side of the picket. Each section uses 2 nails so it does not matter which side you choose to work on first.

Lightly tap on the wood nail with the hammer to begin pushing the nail into the picket. Continue until the nail is fully in the picket.

Repeat until there are 2 nails inserted in the picket at every cross section.
