THE SKEIN / SQUARE SUPPLY INDEX
Thread construction

Does six-strand cotton mean six skeins or48m?
A component count should not become a guaranteed stitching-yield calculation.

Does PearlSize5 divide into five strands?
The size number and the separable-strand count are different specifications.

How should I compare PearlSize5 listings that say15m and25m?
A unit-price comparison needs an exact current put-up,not a shared title.
