| Know before using | A foundational library, not yet an exhaustive stitch encyclopedia. | The record does not create a production grade, supply universal increments or breakpoints, validate a CAD file or fit population, reproduce licensed standards, or replace qualified anthropometric, pattern, technical-design, fit, quality, accessibility, safety, statistical, and user-research review. | 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. |

| What the source establishes | The linked tool or guide is maintained inside Stitch Authority and was checked against its current public interface. | The guide cites current ISO body-table, size-designation, and garment-measurement boundaries plus two peer-reviewed studies that tested the relationship between conventional grade rules, anthropometric evidence, and garment fit; it requires product-specific target deltas and validation instead of publishing universal increments. | 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. |
