Mishnayos Keilim Perek 27 Mishnah 6

אלו נמדדים כפולים – that it needs the measurement to be from two sides. Since it is their manner to use them from two sides, if the measurement is from one side, it is not effective. Another explanation, that it is measured double, that a cloth in the place of cut, it is the manner that the threads go out from it and it becomes ruined and is easily torn, and it is the manner of sewers to double a bit around the cut and sew. And this is measured double as it has been taught, for after it is doubled, there needs to be enough in order to its measurement, but if there isn’t enough for its measurement, even though that if one would loosen the stitch and stretch it out, there would be enough for its measurement. It is not effective.
