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. Seam Allowance Converter

- Primary job: Find patterns & fit
- Area: Patterns & fit

### Best for

Translating a seam allowance already stated by a pattern or controlled specification

### What the source establishes

NIST states that one inch is exactly 25.4 millimetres, and the SI decimal relationship makes one centimetre equal to 10 millimetres. The tool uses those factors, displays rounded equivalents, exposes the size difference to the nearest 1/16 inch when converting to inches, and preserves valid value, source-unit, and target-unit state in the URL.

### Know before using

This is a unit-translation reference. It does not select, approve, or change a seam allowance; establish a universal fraction; interpret an unstated cutting or stitching line; or replace the exact pattern version, controlled specification, material and seam evidence, sample, production method, equipment, tolerance, or release authority.

## 2. Knitting Needle to Crochet Hook Size Chart

### 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.

## 3. Australia Basic Patternmaking Competency

### Best for

Scoping training, hiring, assessment, or evidence requirements for basic textile-product pattern development and testing in Australia

### What the source establishes

Australia's National Training Register publishes current unit MSTAT3002, Develop patterns using basic patternmaking principles. The release document describes interpreting textile-product design specifications, considering fabric performance, selecting tools and equipment, developing patterns, testing the result, and making alterations. Release 1 was generated December 22, 2022 and merged two earlier units. Current Australian apparel and live-production qualifications list MSTAT3002, while the current diploma also exposes advanced individual-fit, alteration, and fit-model units.

### Know before using

This is a competency and assessment reference, not an instructional course, pattern file, qualification by reading, provider recommendation, professional license, or proof that a person can perform the work. The route does not establish enrollment availability, teaching quality, fees, support, recognition outside Australia, or product-specific fit. Confirm the current unit status, packaging rules, prerequisites, registered provider, assessment conditions, local requirements, and actual evidence before relying on it.

## 4. PatternReview

Permanent record: <https://stitchauthority.com/directory/patternreview>
Source page: <https://sewing.patternreview.com/>

- 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.
