# Stitch Authority resource comparison Generated: 2026-07-28T19:49:43.422Z Comparison: This file preserves the published decision metadata for the selected routes. It is not a recommendation, provider approval, compliance decision, or record of project-specific due diligence. ## 1. Knitting Needle to Crochet Hook Size Chart Permanent record: Source page: - Primary job: Learn techniques - Area: Yarn - For: Makers - Location or jurisdiction: Global - Access: Open access - Format: Stitch Authority - Source type: Stitch Authority - Linked page reviewed: 2026-07-28 - Next review due: 2027-07-28 ### Best for Finding the current CYC hook and needle aliases that share one known nominal metric diameter before confirming project gauge ### What the source establishes Rechecked July 28, 2026. The lookup reproduces the current public Craft Yarn Council metric and U.S. alias rows, aligns hooks and needles only when their nominal millimetre value matches, and leaves missing rows or aliases unfilled. ### Know before using A shared nominal diameter does not make a knitting needle and crochet hook interchangeable or predict equal gauge or fabric. The reference is not a physical measurement, manufacturer inspection, UK or Canadian conversion, steel-hook chart, tool recommendation, yarn assignment, or project approval. ## 2. PatternReview Permanent record: Source page: - Primary job: Find patterns & fit - Area: Patterns & fit - For: Makers - Location or jurisdiction: Global - Access: Free + paid - Format: Community - Source type: Community database - Linked page reviewed: 2026-07-28 - Next review due: 2027-01-24 ### Best for Finding member reports about a named sewing pattern ### What the source establishes PatternReview's current site exposes recent pattern, sewing-machine, and store reviews, forums, contests, classes, classifieds, a pattern shop, and a searchable review gallery. Its account FAQ says most participation requires a free activated account. Friends of PR adds advanced search, a personal pattern catalogue and wishlist, bookmarks, classifieds, a photo album, discounts, and other features through a recurring paid membership with a published email cancellation route. ### Know before using PatternReview combines community reports, membership, education, advertising, and retail, so it is not a neutral or complete pattern index. Reviews are individual experiences rather than standardized fit tests. Confirm the exact pattern version, size range, measurements, fabric, format, errata, licence, seller terms, and current availability with the designer or publisher. Paid catalogue and search features do not establish an export route or continued access after membership ends. ### Account, payment, and exit - Access scope: Sewer reading community pattern reports, participating in discussions, or keeping a personal pattern catalogue and wishlist. - Before an account: Browse recent pattern reviews, the review gallery, shop, classes, blog, and public help pages without creating an account. - Free-account boundary: Free membership requires email activation. The account FAQ says most participation and member-only areas require sign-in. - Payment boundary: Friends of PR costs $34.95 per year and adds advanced search, a personal pattern catalogue and wishlist, bookmarks, classifieds, discounts, and other features. - Cancellation or exit: Friends of PR recurs on its plan cycle. The account FAQ says an advance email includes cancellation instructions and also publishes an email cancellation route. - Saved work and data: Paid tools can hold a pattern catalogue, wishlist, bookmarks, and photos, but the checked pages do not establish a complete export or post-membership retention route. Keep critical records elsewhere. ## 3. Pattern Grading & Size-Run Validation Record Permanent record: Source page: - Primary job: Find patterns & fit - Area: Patterns & fit - For: Apparel brands - Location or jurisdiction: Global - Access: Open access - Format: Stitch Authority - Source type: Stitch Authority - Linked page reviewed: 2026-07-27 - Next review due: 2027-07-27 ### Best for Auditing inherited grade rules or controlling a new multi-size pattern release from approved targets through sample evidence ### What the source establishes 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. ### Know before using 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. ## Next checks 1. Remove any route whose audience, jurisdiction, access, or scope does not match the job. 2. Open the permanent record and source page for every remaining route. 3. Recheck facts that can change after the listed review date. 4. Verify project-specific capability, terms, test evidence, and legal requirements with the responsible source or provider. 5. Record the reason for the final choice outside Stitch Authority.
