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.

### Best for

Custom-fit home sewing patterns

### What the source establishes

FreeSewing's official documentation says the browser editor drafts a selected design in real time from a measurement set rather than scaling or grading a standard-size pattern. Users can adjust design options and export the generated result, including as PDF; saving the pattern to an account is optional and is used to revisit it later.

### Know before using

A generated pattern is not independent fit evidence or a production-ready graded block. The result still depends on accurate measurements, the selected design and options, ease assumptions, fabric behavior, construction, and representative test garments. An account stores saved patterns and measurement sets, so review the platform's privacy terms before retaining personal measurements.

## 2. Lectra Modaris

### Best for

Enterprise pattern rooms and supplier file exchange

### What the source establishes

Lectra's current Modaris page identifies version 2025.2 as the latest listed release and describes a one- to three-year subscription with two releases per year. The modular range covers base-pattern creation and modification, grading and industrialization, native-file supplier work, pattern libraries, synchronized 2D and 3D prototypes, configurable or imported mannequins, and separate conversion and consumption-estimate add-ons.

### Know before using

The page does not publish price and its product-quality, error-prevention, data-loss, and fit statements are vendor claims. Capabilities vary across Essential, Classic, Expert, 3D, and add-ons. Confirm licenses, modules, support, system and file requirements, then pilot approved blocks, grade rules, supplier reopen, material and mannequin data, plot or cut outputs, and risk-appropriate physical fit and production checks.

## 3. Threadloop Sewing Pattern Database

Permanent record: <https://stitchauthority.com/directory/threadloop>

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

- Source type: Community database

### Best for

Searching current and out-of-print sewing patterns

### What the source establishes

Threadloop's official guide describes an independent, fully crowdsourced database covering available and out-of-print sewing patterns. Its search supports pattern type, fabric type, age group, body type, cup size, level, format, file features, language, measurements, availability, and other filters; members can also track a stash, wishlist, projects, reviews, and discussions.

### Know before using

Community members add and quality-control the records, so confirm sizing, measurements, fabric suggestions, format, availability, errata, license, and purchase terms with the designer or publisher. Adding an entry to a stash does not provide the pattern files. Saved searches and private PDF storage are paid Plus features, and a listing or review does not establish pattern accuracy or fit.

## 4. Controlled Tech Pack Orientation

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: 2026-07-16
- Next review due: 2027-07-16

### Best for

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

### What the source establishes

The guide cites current ISO sources for documented-information, garment-measurement, stitch, and seam boundaries plus current U.S. FTC textile and care-labeling guidance; it explicitly separates those authorities 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.
