### Best for

Finding sustainability-focused suppliers and guidance

### What the source establishes

Common Objective currently offers free individual and business profiles, personalised matches, supplier and content search, and limited monthly connection requests. Paid tiers unlock unlimited connections, additional content, training credits, and the CO Create sourcing workflow. Businesses enter their own profile information and upload certification or membership evidence; profile completeness, sustainability material, training credits, awards, and paid capabilities can influence visibility or ranking.

### Know before using

A profile, match, uploaded credential, training credit, award, or platform ranking is not independent certification of a supplier or proof of current capability, performance, impact, capacity, or project fit. The platform's own ranking inputs and paid visibility affect discovery. Verify credentials with the issuer and check the legal entity, production site, claims, samples, references, terms, and compliance directly.

### Account, payment, and exit

- Access scope: Fashion professional or supplier using content, profiles, connections, or a sourcing workflow.
- Before an account: Public content and explanation pages are visible while signed out; profiles, personalized matches, saved items, and connections require signup.
- Free-account boundary: A free account provides a personal or business profile, limited monthly connections, free content, and up to three portfolio items.
- Payment boundary: PRO adds unlimited connections, paid content and training, more profile capacity, and business sourcing workflows. Monthly and annual routes use provider-set terms.
- Cancellation or exit: Cancel in the account by selecting downgrade. A business profile returns to the free version and only its first three portfolio items remain visible.
- Saved work and data: Profiles can contain files, work history, product galleries, and sustainability evidence. The current access and pricing pages do not establish full export or deletion; retain originals.

## 2. 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

### 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.

## 3. PatternLab London

Permanent record: <https://stitchauthority.com/directory/patternlab-london>
Source page: <https://patternlab.london/home/>

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

### Best for

Generating an editable custom-measurement block

### What the source establishes

PatternLab London's current drafting page says a user creates a measurement profile, selects a basic block or sloper, adjusts fit, dart placement, length, seam allowance, and sleeve options, then downloads the generated result as tiled PDF, AI, or SVG. The live catalogue names bodice, dress, trouser, and stretch blocks and displays a price before purchase.

### Know before using

A measurement-generated draft is a starting block, not independent evidence of body capture, comfort, mobility, balance, garment ease, or production fit. The result depends on measurement accuracy, supported ranges, formula assumptions, selected options, and output handling. Review the service's privacy terms before storing body data and sew a representative toile before design, grading, or production use.

## 4. Threadloop Sewing Pattern Database

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

### 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.

## 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.
