The cloth industry
The chief uses of woven cloth at the time were clothing and sails for ships and windmills. The clothing made by this method was so durable that it would often last longer than the person wearing it and be beqeathed to heirs. The raw materials were high quality and the skills of the tailor (kleermaker) were extraordinary.
One of the measures of fabric quality is the thickness and density of the threads. Since there was so little standardization, merchants like van Leeuwenhoek relied on their own eyes, aided by a thread counter (dradenteller). It is a low-powered lens, like a jeweler's loupe, magnifying perhaps three to five times, with resolution good enough to calibrate and count even the thinest threads.
