Methods and examples
Calculators identify usable dimensions, repeats, shrinkage, allowances, unit conversions, rounding, and the difference between geometric estimates and production markers. Important examples are checked against the same functions used by the page.
Production limits
Fabric lot, conditioning, construction, finish, nap, grain, defects, equipment, marker rules, and operator practice can change results. Samples, test reports, markers, and supplier specifications control.
Review dates
Dates change only after substantive review. No public corrections channel is configured, so no contact identity is invented.
