### Best for

Searching global apparel and textile production capabilities

### What the source establishes

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.

### Know before using

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.

### Best for

Following a structured classroom introduction to womenswear block development, muslin test fitting, fit correction, and basic flat-pattern manipulation

### What the source establishes

CBSE's official publication index links the Class XII Fashion Studies textbook. Its Basic Pattern Development chapter covers body and dress-form measurement, size relationships, patternmaking tools and terms, fit and balance, muslin test fitting, block correction, bodice, sleeve and skirt blocks, seam allowances, grain lines, notches, necklines, collars, and dart manipulation. The stated learning outcomes include developing blocks from charts and body measurements, testing fit, correcting the pattern, and developing simple designs from basic blocks.

### Know before using

This is a classroom textbook with particular womenswear exercises, charts, figures, terminology, units, and drafting methods. It is not a universal body, block, grading, or sizing system; current industry certification; or proof of fit for an individual wearer or product. Some content and examples predate the current review. Verify the intended body data, measurement protocol, ease, material, seam and construction rules, accessibility, current curriculum status, and representative sewn fit independently.

## 3. Yarn Substitution Planner

Permanent record: <https://stitchauthority.com/directory/yarn-substitution-planner>
Source page: <https://stitchauthority.com/tools/yarn-substitution-planner>

- Primary job: Choose materials
- Area: Yarn
- For: Makers
- Location or jurisdiction: Global
- Access: Open access
- Format: Stitch Authority
- Source type: Stitch Authority
- Linked page reviewed: 2026-07-16
- Next review due: 2027-07-16

### Best for

Turning a known project length and candidate package size into a transparent buying estimate while keeping specimen, finished-fabric, care, and supply decisions separate

### What the source establishes

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.

### Know before using

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.

## 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.
