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. SwatchOn

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

- Primary job: Choose materials
- Area: Materials
- For: Apparel brands
- Location or jurisdiction: Global
- Access: Free account
- Format: Marketplace
- Source type: Commercial marketplace
- Linked page reviewed: 2026-07-28
- Next review due: 2027-01-24

### Best for

Sourcing swatches and low-MOQ fabric options

### What the source establishes

SwatchOn's current marketplace page exposes fabrics, trims, and prints, with swatch samples, in-stock catalogue colours, low-order-quantity options, and global logistics support. Current account guidance places the full product library, wholesale ordering, and sample purchasing behind email verification, while the terms describe supplier-provided listings, per-order payment, cross-border charges, sample limits, and marketplace responsibility.

### Know before using

SwatchOn's supplier status, counts, trust language, specifications, prices, availability, and account benefits are provider or supplier statements that can change. They do not independently establish fibre identity, performance, certification validity, mill ownership, production capacity, colour continuity, delivery, duty, or commercial fit. Review representative samples, test data, current certificates, the contracting entity, order terms, return limits, and landed logistics before purchase.

### Account, payment, and exit

- Access scope: Business or individual buyer sourcing fabric, trims, swatches, or custom printing through SwatchOn's marketplace and order workflow.
- Before an account: Read the marketplace scope, material-category pages, service explanations, help articles, calculators, and legal policies. The checked signed-out pages do not expose the full product library, wholesale ordering, or sample-purchase workflow.
- Free-account boundary: After email verification, business and individual accounts receive product-library, wholesale-order, and sample-purchase access. A completed business profile and business proof add a sourcing manager and conditional swatch credits; the terms allow identity, business, or payment verification and account rejection.
- Payment boundary: The checked first-party pages disclose no recurring platform subscription. Buyers pay per sample or product order plus the checkout currency, shipping, duties, taxes, adjustments, and any agreed service fees; complimentary swatches or credits are conditional rather than universal free access.
- Cancellation or exit: There is no subscription plan to cancel on the checked pages. The terms say a user may stop using the platform, while the privacy policy routes access, correction, portability, and deletion requests through support and permits retention for legal, accounting, dispute, and agreement-enforcement needs.
- Saved work and data: The platform can hold account and verification data, carts and orders, payment and shipping records, customs documents, artwork, supplier messages, reviews, and support tickets. The privacy policy offers copy, portability, correction, and deletion requests, but does not state a self-service full export, exact format, completion time, or complete deletion of retained transaction records.

## 2. Threadloop Sewing Pattern Database

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

- 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

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. Current terms state that the free plan requires no card, paid upgrades start billing immediately, cancellation retains paid features through the current cycle, and the account then returns to free features.

### 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.

### Account, payment, and exit

- Access scope: Sewer searching pattern records or organizing patterns, projects, fabric, notions, and private files.
- Before an account: Browse the pattern database, guide, designers, publications, and public community areas without creating an account.
- Free-account boundary: A free account needs no card and supports a stash, wishlist, projects, reviews, and personal organization.
- Payment boundary: Plus adds PDF pattern storage, collections, saved searches, bulk editing, and other workflow features on monthly or annual billing.
- Cancellation or exit: Cancel through an in-account link. Paid features remain through the current billing cycle, then the account returns to free features.
- Saved work and data: The terms say submitted materials remain yours, but the checked public pages do not explain a full export or how stored PDFs behave after downgrade. Keep originals outside the platform.

## 3. Pattern Grading & Size-Run Validation Record

Permanent record: <https://stitchauthority.com/directory/grading-guide>
Source page: <https://stitchauthority.com/guides/pattern-grading-explained>

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

Auditing inherited grade rules or controlling a new multi-size pattern release from approved targets through sample evidence

### What the source establishes

The guide cites current ISO body-table, size-designation, and garment-measurement boundaries plus two peer-reviewed studies that tested the relationship between conventional grade rules, anthropometric evidence, and garment fit; it requires product-specific target deltas and validation instead of publishing universal increments.

### Know before using

The record does not create a production grade, supply universal increments or breakpoints, validate a CAD file or fit population, reproduce licensed standards, or replace qualified anthropometric, pattern, technical-design, fit, quality, accessibility, safety, statistical, and user-research review.

## 4. Optitex 2D/3D Pattern Design

Permanent record: <https://stitchauthority.com/directory/optitex-pds>
Source page: <https://optitex.com/products/2d-and-3d-cad-software/>

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

### Best for

Integrated pattern, marker, and 3D production workflows

### What the source establishes

Optitex's current page describes 2D pattern creation, grading, verification, Tech Pack Essentials, marker creation and nesting, cut and plot output, 3D virtual samples, fabric simulation, colour and print placement, tension maps, and avatar editing. Its support page lists native and standard CAD interchange routes and states that Optitex does not support macOS.

### Know before using

Pricing is not public, modules and system requirements must be confirmed, and macOS is not supported. Vendor accuracy and fit language does not prove results for an actual product. Pilot native and exchanged files with the receiving supplier, calibrated materials, approved blocks and grade rules, marker and output devices, tech-pack fields, training, version control, and risk-appropriate physical fit and production checks.

## 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.
