| Best for | Building a substitution shortlist for a discontinued or unavailable yarn before checking quantity, availability, and a representative swatch | Turning an ambiguous POM name, code, or diagram into a reproducible method before setting targets, tolerances, or inspection decisions | Planning the current CPSC certificate-data handoff for regulated imports with the importer, finished-product certifier, customs broker, and entry records | Digital pattern drafting |
| Know before using | A suggested match is a data-based shortlist, not proof that the yarn suits the pattern or maker. Records can be incomplete or wrong, price bands are approximate, availability varies by country and seller, and shade-level matching is unavailable. YarnSub says affiliate status does not change suggestions, but equally rated matches are ordered by brand popularity. Confirm required gauge, total length, fibre behavior, construction, care, colour, dye lot, accessibility, price, availability, and seller terms, then make and assess a representative swatch before committing. | The record does not reproduce licensed ISO measurement drawings, supply universal POM codes or targets, approve an internal method, prove measurement capability or product fit, or replace qualified technical-design, pattern, fit, quality, metrology, safety, and regulatory review. | The portal does not decide whether a product requires certification, identify the correct rules or certificate data, classify an entry, replace the current 16 CFR part 1110 text, or reconcile a filing to an actual shipment. Effective dates and workflows differ by entry route; use current CPSC, CBP, customs, product-safety, and legal review. | Patternmaking knowledge, controlled measurement files, production conventions, and sewn fit testing are still required. The software does not validate body measurements, ease, balance, grading rules, fabric behavior, construction, or product fit. The project currently labels its user wiki manual as needing updates, so confirm current commands and file behavior against the installed release and active support channels. |

| Source and review | ||||
| What the source establishes | YarnSub's official FAQ says its matching software compares gauge, texture, yarn weight and density, fibre content, and fibre qualities such as drape and softness. Discontinued yarns remain searchable as starting points but are excluded from suggestions. Result filters can exclude animal, animal-derived, synthetic, or plant fibre groups and use a subjective $ to $$$$$ price indicator. The site does not accept user-entered yarn details, individual shade cards, or expose an API. Each yarn page provides a data-issue route. | The guide cites current ISO garment-measurement, body-measurement, and textile-conditioning standards plus NIST measurement-process guidance for repeatability and reproducibility; it requires organization-specific codes, added points, targets, and tolerances to remain explicitly controlled. | CPSC operates the eFiling portal with role-specific importer, broker, applicability, Product Registry, regulated-product, laboratory, ACE, FAQ, video, and document-library routes. The certificate final rule took effect July 8, 2026 for covered non-FTZ products, with separate timing for covered FTZ entries. | The maintained Seamly2D repository identifies the application as GPLv3+ open-source patternmaking software for Windows, macOS, and Linux. It reads multi-size measurement files for standardized sizes and individual measurement files for custom-fit work, publishes downloadable builds and releases, and links an active website and user forum. |
