| Best for | Understanding what a tech pack must control before using a template or releasing work | Searching global apparel and textile production capabilities | Turning a known project length and candidate package size into a transparent buying estimate while keeping specimen, finished-fabric, care, and supply decisions separate | Free editorial knitting patterns and techniques |
| Know before using | 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 company count is a changing platform claim. Search fields, profiles, certificates, locations, and account access do not independently verify the legal entity, factory ownership, capability, capacity, certificate validity or scope, compliance performance, delivery, or project fit. Confirm the site and subcontracting, credentials with issuers, samples, audits when appropriate, specifications, contracts, and commercial terms. | The tool does not verify label values, convert between metres and yards, identify fibre or yarn diameter, assign a yarn-weight category, predict gauge or fabric, prescribe reserve, guarantee required quantity, check dye-lot supply, score candidates, or approve a substitution. A representative treated specimen and project-specific fabric, care, wear, comfort, supply, and quantity review remain required. | Free access does not grant commercial reproduction or sale rights; uses beyond one personal copy must be resolved with the designer or author. Knitty says it tries to avoid errors but disclaims responsibility for pattern and technique inaccuracies. Check the live page for corrections, verify gauge and measurements, and confirm permission before any commercial use. |

| What the source establishes | 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. | FOURSOURCE's current public network page presents an operator-reported global company count and country or territory search. It says logged-in users can narrow results by compliance certificates, product groups, fabric types, target groups, minimum order quantities, and other fields, with a free-trial and supplier sign-up route. | The planner performs visible arithmetic only on user-entered project length, reserve, package length, package mass, and price. Its connected source-reviewed guide cites the current Craft Yarn Council category, FAQ, WPI, and hook-and-needle guidance plus ASTM and ISO linear-density sources, and explicitly separates label comparison from substitution approval. | Knitty currently publishes web-only editorial issues containing original knitting and crochet patterns and articles. Its legal page states that patterns are free for one person's personal use, identifies each designer or author as the copyright holder, and explains that verified pattern corrections are posted in bright pink on the pattern page. |
