How do you run a fence string line?

Typically, to run a string line you already have installed your first and last fence posts. Begin the stringing process by measuring up on the first and last fence posts to the point where you want your top rail to attach. Once you've identified that placement, fasten a small screw or nail to the post on both ends, then secure the string to the screws. Be sure the string is pulled tight so it doesn't drop down the fence line. Set the remainder of your posts and plumb them as needed before the concrete in the post hole cures. Usually, you'll want line posts to touch but not deflect the string line otherwise your posts won't line up after the concrete is dry. Setting posts properly isn't hard, but it does take time and patience to make sure they are plumb and flush with the fence line. Step back far enough to look at the string line and see if you like how the top line of your fence will look. If there are any transitions in your property grade, you may want to measure up applicable line posts and attach additional screws. Move the string line so the screw acts as another contact point to alter the angle of the line. Step back several times and get a good view of the string line and make any additional adjustments before finalizing the measurements for the rest of your brackets based on the location of the string.
