| Best for | Finding the current CYC hook and needle aliases that share one known nominal metric diameter before confirming project gauge | Browsing and buying indie sewing patterns | Understanding what a tech pack must control before using a template or releasing work |
| 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. | This is a retailer-curated catalogue, not a complete or neutral index of sewing patterns. Customer reviews are individual reports rather than standardized fit testing, and each designer controls sizing, instructions, licence, format, errata, and support. Confirm the exact size range, cup options, finished measurements, file format, and usage terms on the product page before purchase. | 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. |

| 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. | The Fold Line's current shop and about page expose a curated catalogue of more than 7,000 sewing patterns from over 200 independent designers, a pattern finder, customer reviews, paper and digital PDF formats, and an optional large-format copy-shop printing service with worldwide shipping. | The guide cites published ISO sources for documented-information, garment-measurement, stitch, and seam boundaries plus current U.S. FTC textile and care-labeling guidance; it discloses that ISO 10013:2021's 2026 systematic review is at close-of-review stage and separates every cited authority from product-specific technical and market decisions. |
