Merchants used magnifying lenses to count the threads in woven linen cloth. In 1654, Leeuwenhoek returned to Delft and opened his own business as a fabric salesman. With his microscopes, Leeuwenhoek observed bacteria, protozoa, ant pupae, and many other tiny organisms.
Most likely to find the thread count of the fabric or cloth.
Explanation:
A higher thread count indicates a softer material, meaning they can charge more for it because people will be willing to pay more for a more comfortable material. A lower thread count indicates a coarser or rougher material, which is more durable but is not as comfortable. People will likely be less willing to pay a higher price for it.
