### 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.

## 2. 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

### 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.

## 3. Handweaving.net Draft Archive

Permanent record: <https://stitchauthority.com/directory/handweaving-net>
Source page: <https://handweaving.net/>

- Primary job: Learn techniques
- Area: Techniques & repair
- For: Makers
- Location or jurisdiction: Global
- Access: Free + paid
- Format: Reference

- Linked page reviewed: 2026-07-28

### Best for

Researching loom-ready weaving structures and drafts

### What the source establishes

Handweaving.net currently exposes the Ralph Griswold digital archive, document downloads, draft drawdown views, basic-account clipboards, and video tutorials without a paid subscription. Its subscription page reserves full drafts, WIF downloads, draft creation and editing, color tools, profile and block substitution, arrangement, repeats, and related browser tools for subscribers. The current page states that plans renew until canceled, cancellation takes effect at the next renewal, access remains until then, and refunds are not offered.

### Know before using

A visible drawdown is not automatically a complete, corrected, rights-cleared, or loom-compatible project plan. Full draft data and advanced tools require a renewing subscription, and historical sources can contain errors or unclear provenance. Check shafts, treadles, tie-up, sett, yarn, floats, repeats, copyright status, and WIF compatibility before committing a warp.

### Account, payment, and exit

- Access scope: Weaver deciding whether viewing a draft is enough or a working WIF file and editing tools are required.
- Before an account: Browse the Ralph Griswold archive, download archive documents, and view draft drawdowns without a paid subscription.
- Free-account boundary: A free basic account adds clipboards. Full drafts, working files, and browser drafting tools remain outside the free account.
- Payment boundary: A monthly or annual recurring subscription unlocks full drafts, WIF downloads, and browser drafting and editing tools.
- Cancellation or exit: Cancel from the account page. Renewal stops at the next renewal date, paid access remains until then, and the provider states that refunds are not given.
- Saved work and data: The checked page does not explain bulk export or deletion for clipboards or contributed drafts. Retain local copies of WIF files and source material before exit.

## 4. FOURSOURCE Supplier Network

Permanent record: <https://stitchauthority.com/directory/foursource>
Source page: <https://www.foursource.com/explore-network/>

- Primary job: Source production
- Area: Production
- For: Apparel brands
- Location or jurisdiction: Global
- Access: Free account
- Format: Marketplace
- Source type: Commercial marketplace
- Linked page reviewed: 2026-07-21

### 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.

## 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.
