Well, there is the thread counter, a loupe for - who might have guessed - counting threads in woven fabric.


This one I inherited from my grandmother who was a master tailor. The square opening measures 30mm X 30mm, so one can count the threads within the square (or half of it, there are small incised markings on the centres of the sides) and divide 30mm (or 15mm) by that number to get the diameter of a single thread.
