Running stitch in pantyhose: hair spray
Hairspray helps against running in fine tights.
To prevent, just spray the tights with hairspray. Even if it is already too late, just spray hairspray on the affected area.
Just no hair spray ready? No problem. To prevent you can put the tights in the freezer. If something happens then, no problem. With nail polish, the run is no longer bigger.
And that woman has actually mostly at hand! * Grin *
