| Know before using | 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. Saved searches and private PDF storage are paid Plus features, and a listing or review does not establish pattern accuracy or fit. | An orientation rather than a completed product record; it does not supply a universal format, licensed standard content, measurements, tolerances, construction settings, labels, approvals, compliance conclusion, or product-release authority. | The guide's general womenswear diagrams and ease ranges are teaching examples, not an individual diagnosis, current commercial-pattern specification, or complete fitting course. A named symptom can have several causes, and alterations may affect adjoining seams, facings, collars, sleeves, balance, and style. Verify the method against the exact pattern and test the coordinated changes on a muslin. | A foundational library, not yet an exhaustive stitch encyclopedia. |

| What the source establishes | 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 guide cites current ISO sources for documented-information, garment-measurement, stitch, and seam boundaries plus current U.S. FTC textile and care-labeling guidance; it explicitly separates those authorities from product-specific technical and market decisions. | New Mexico State University's current Cooperative Extension Guide C-228 explains three alteration methods, folding out fullness, slashing and spreading or overlapping, and redrawing darts or seams. It provides illustrated bodice, sleeve, skirt, and trouser examples and tells readers to compare body measurements plus intended ease with the pattern while preserving grain, design lines, related-piece changes, and comfort ease. | The linked tool or guide is maintained inside Stitch Authority and was checked against its current public interface. |
