Anotations

Scope note:

Magnifying tools, comprising a rotatable magnifying lens mounted a fixed distance above a platform on which textile materials can be examined, designed to count woven fabric threads within a given space or texture. To measure the thread count of a fabric sample, these optical devices work to enlarge the user's view of the fabric's warp and weft threads so the fabric quality can be more easily determined.
