Remove hosiery that already has a small run or snag as soon as possible. Place your hand into the leg of the tights where the run is and paint a dot of clear nail polish on the edges of the tear. Allow the tights to dry completely before wearing.  It’s important that you have your hand or another object like a piece of cardboard or paper in between the two layers of the tights, as you do not want the nail polish to stick the two sides together as it dries. You can use colors other than clear for the nail polish, but it should match the color of the tights or not show a visible difference. Have a washcloth and nail polish remover on hand for any accidents, and avoid getting nail polish on your skin at all costs. Apply hairspray to the beginning of a run to keep it from spreading any wider. Spray on the thinnest layer possible, as you don’t want your tights to get sticky or gunky.  You can also use hairspray as a preventative treatment. Spray a very thin coat across the entire surface of your tights to help strengthen the fibers against snags and runs.  Note that unlike nail polish, hairspray will wash away, so keep water away from your tights while you’re wearing them and reapply hairspray as needed after a wash cycle. Brush Wite-Out onto the beginnings of a small run in your tights. Apply to the edges of the run just like you would with the nail polish method.  Use this treatment only if your run is in an unnoticeable area or if your tights are white, otherwise the Wite-Out can stand out too much. Note that Wite-Out also washes out, so it will need to be reapplied after exposure to water. If any fibers in your tights are loose or sticking out, trim them very carefully by pinching the fabric around the loose thread and then cutting it away at the base. This will prevent loose fibers from getting caught and snagged in the future. Note that cutting at threads could cause unraveling and weakening of nearby fibers. Apply a dab of clear nail polish to the area before or after cutting. Buy tights in multi-packs of the same weight and color. If you get irreparable runs in the right leg of one pair and the left leg of another, simply cut off the ruined leg on each and wear the two pairs together to look like one single, run-free pair.  This tip allows you to conserve and get more use out of the same pair of tights so you don’t have to buy new ones as often. Don’t cut into the upper portion of the tights that goes around your hips and waist. In other words, don’t convert your tights into thigh-highs while you’re cutting; keep the waist so that each leg stays up.
