## 1. 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.

## 2. Australia Basic Patternmaking Competency

Permanent record: <https://stitchauthority.com/directory/australia-basic-patternmaking-competency>

- Primary job: Find patterns & fit
- Area: Patterns & fit
- For: Both
- Location or jurisdiction: Australia · Oceania
- Access: Open access
- Format: Reference
- Source type: Official registry
- Linked page reviewed: 2026-07-16

### Best for

Scoping training, hiring, assessment, or evidence requirements for basic textile-product pattern development and testing in Australia

### What the source establishes

Australia's National Training Register publishes current unit MSTAT3002, Develop patterns using basic patternmaking principles. The release document describes interpreting textile-product design specifications, considering fabric performance, selecting tools and equipment, developing patterns, testing the result, and making alterations. Release 1 was generated December 22, 2022 and merged two earlier units. Current Australian apparel and live-production qualifications list MSTAT3002, while the current diploma also exposes advanced individual-fit, alteration, and fit-model units.

### Know before using

This is a competency and assessment reference, not an instructional course, pattern file, qualification by reading, provider recommendation, professional license, or proof that a person can perform the work. The route does not establish enrollment availability, teaching quality, fees, support, recognition outside Australia, or product-specific fit. Confirm the current unit status, packaging rules, prerequisites, registered provider, assessment conditions, local requirements, and actual evidence before relying on it.

## 3. Swatch-to-Area Yarn Estimator

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

- 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: 2026-07-28
- Next review due: 2027-07-28

### Best for

Documenting a bounded sample-to-area yarn calculation when the equivalent area is already known and genuinely comparable with the sample

### What the source establishes

The worksheet performs visible proportional arithmetic on user-entered sample dimensions, sample yarn length or weight-derived length, equivalent area, and optional reserve. Craft Yarn Council pattern-writing guidance says yarn amounts and package counts should be recorded in instructions, and its consumer guidance ties project instructions to a stated yarn amount and representative gauge; those sources do not establish a universal sample-to-area method, project range, or reserve. NIST defines 1 yard as exactly 0.9144 metre for the secondary unit display.

### Know before using

The worksheet does not establish that a sample represents a project, derive the area of shaped pieces, account for construction or openings, prescribe reserve, supply typical project quantities, round to packages, verify label values, guarantee required quantity, check dye-lot supply, or replace a tested pattern amount. Yarn, tool, maker, strand count, stitch or texture, density, treatment, finishing, planned area, and supply decisions remain project-specific.

## 4. Seamly2D

Permanent record: <https://stitchauthority.com/directory/seamly>
Source page: <https://seamly.io/>

- Primary job: Find patterns & fit
- Area: Patterns & fit
- For: Both
- Location or jurisdiction: Global
- Access: Free download
- Format: Software
- Source type: Open-source project
- Linked page reviewed: 2026-07-21
- Next review due: 2027-01-17

### Best for

Digital pattern drafting

### What the source establishes

The maintained Seamly2D repository identifies the application as GPLv3+ open-source patternmaking software for Windows, macOS, and Linux. It reads multi-size measurement files for standardized sizes and individual measurement files for custom-fit work, publishes downloadable builds and releases, and links an active website and user forum.

### Know before using

Patternmaking knowledge, controlled measurement files, production conventions, and sewn fit testing are still required. The software does not validate body measurements, ease, balance, grading rules, fabric behavior, construction, or product fit. The project currently labels its user wiki manual as needing updates, so confirm current commands and file behavior against the installed release and active support channels.

## 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.
