### Best for

Comparing a patternmaking curriculum, qualification claim, learning plan, or portfolio brief with Peru's published national program competencies and achievement indicators

### What the source establishes

Peru's Ministry of Education currently lists Patronaje under garment manufacturing in the National Catalogue of Training Offerings, whose industry-manufacturing orientation page records a last change on June 4, 2026. The official program is code C0714-2-002 at technical level, with 80 credits and 1,760 hours. Its seven competency units cover obtaining base and graded garment patterns from a technical specification; preparing, sewing, and validating a prototype; manually or digitally laying out pattern pieces; spreading material; cutting; preparing cut pieces for production; and joining garment pieces. The connected achievement indicators name specifications, measurements, seam information, trims, finishes, base size and scale, client requirements, material optimization, cutting orders, occupational safety, and production handoff.

### Know before using

This is a national program reference whose published program version is marked updated November 6, 2018, although Minedu still lists Patronaje in the current CNOF. It is not a current course-opening directory, enrollment offer, school recommendation, complete syllabus, teaching-quality assessment, professional license, practitioner certification, ready pattern, universal size or grading system, product-fit proof, or evidence that an individual completed the competencies. Confirm the current catalogue status, authorized institution, offered plan, admission, delivery, assessment, title, local recognition, equipment, software, safety, cost, accessibility, and product-specific pattern and fit evidence directly.

## 2. Pattern Testers

Permanent record: <https://stitchauthority.com/directory/pattern-testers>
Source page: <https://patterntesters.com/>

- Primary job: Find patterns & fit
- Area: Patterns & fit
- For: Apparel brands
- Location or jurisdiction: Global
- Access: Free + paid
- Format: Software
- Source type: First-party platform
- Linked page reviewed: 2026-07-21
- Next review due: 2027-01-17

### Best for

Coordinating an independent sewing-pattern test

### What the source establishes

Pattern Testers currently offers application intake, tester selection, feedback, photos, approvals, issue tracking, revisions, a reusable tester directory, and release deadlines. The public pricing page shows a limited free plan and paid Pro and Business tiers. Its June 2026 privacy policy lists names, email addresses, measurements, photos, feedback, application history, and assignments among the data processed.

### Know before using

The interface and plan description do not prove tester reach, completion, feedback quality, fit validity, export quality, uptime, support, or suitability for an established release process. Measurements and photos can be sensitive personal data. Run a non-critical pilot, review the current privacy and service terms, define consent and photo rights, test exports and deletion, and keep pattern approval and release responsibility with the designer.

## 3. YarnSub

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

- Primary job: Choose materials
- Area: Yarn
- For: Makers
- Location or jurisdiction: Global
- Access: Open access
- Format: Reference
- Source type: First-party platform
- Linked page reviewed: 2026-07-28
- Next review due: 2027-01-24

### Best for

Building a substitution shortlist for a discontinued or unavailable yarn before checking quantity, availability, and a representative swatch

### 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.

### 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.

### Account, payment, and exit

- Access scope: Maker comparing a replacement for a named yarn before buying.
- Before an account: Search a named yarn, inspect suggested substitutes, and filter by fibre and approximate price band without creating an account.
- Free-account boundary: The checked core substitution route does not require an account, and the FAQ does not offer user-entered yarn records.
- Payment boundary: No subscription is presented for the core route. Affiliate retailer links and optional donations help fund the site; equal-rated matches are ordered by brand popularity.
- Cancellation or exit: There is no account or recurring plan to cancel for the core route. The newsletter has a separate unsubscribe link.
- Saved work and data: YarnSub does not expose an API and does not accept user-entered yarn details. Use the data-issue link on a yarn page for corrections.

## 4. Tech Pack Definition, Contents & Limits

Permanent record: <https://stitchauthority.com/directory/tech-pack>
Source page: <https://stitchauthority.com/guides/what-is-a-tech-pack>

- Primary job: Source production
- Area: Production
- 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

Understanding what a tech pack must control before using a template or releasing work

### What the source establishes

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.

### 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.

## 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.
