Know before usingThe planner adds and rounds user-entered lengths; it does not create a cutting layout, infer shrinkage or matching allowances, compensate for a width change, establish usable width, or prove that the order quantity is sufficient.Community members add and quality-control the records, so confirm sizing, measurements, fabric suggestions, format, availability, errata, license, and purchase terms with the designer or publisher. Adding an entry to a stash does not provide the pattern files.

Source and review
What the source establishesNIST defines 1 yard as exactly 0.9144 metre. Sewing & Craft Alliance guidance ties an applicable cutting layout to the exact view, size, fabric width, and nap condition and recommends layout work when listed conditions do not fit the project.Threadloop's official guide describes an independent, fully crowdsourced database covering available and out-of-print sewing patterns. Its search supports pattern type, fabric type, age group, body type, cup size, level, format, file features, language, measurements, availability, and other filters; members can also track a stash, wishlist, projects, reviews, and discussions.The linked tool or guide is maintained inside Stitch Authority and was checked against its current public interface.
