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

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

### What the source establishes

The guide cites published ISO sources for documented-information, garment-measurement, stitch, and seam boundaries plus current U.S. FTC textile and care-labeling guidance; it discloses that ISO 10013:2021's 2026 systematic review is at close-of-review stage and separates every cited authority 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.

## 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

### 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. PatternReview

Permanent record: <https://stitchauthority.com/directory/patternreview>
Source page: <https://sewing.patternreview.com/>

- 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

Finding member reports about a named sewing pattern

### What the source establishes

PatternReview's current site exposes recent pattern, sewing-machine, and store reviews, forums, contests, classes, classifieds, a pattern shop, and a searchable review gallery. Its account FAQ says most participation requires a free activated account. Friends of PR adds advanced search, a personal pattern catalogue and wishlist, bookmarks, classifieds, a photo album, discounts, and other features through a recurring paid membership with a published email cancellation route.

### Know before using

PatternReview combines community reports, membership, education, advertising, and retail, so it is not a neutral or complete pattern index. Reviews are individual experiences rather than standardized fit tests. Confirm the exact pattern version, size range, measurements, fabric, format, errata, licence, seller terms, and current availability with the designer or publisher. Paid catalogue and search features do not establish an export route or continued access after membership ends.

### Account, payment, and exit

- Access scope: Sewer reading community pattern reports, participating in discussions, or keeping a personal pattern catalogue and wishlist.
- Before an account: Browse recent pattern reviews, the review gallery, shop, classes, blog, and public help pages without creating an account.
- Free-account boundary: Free membership requires email activation. The account FAQ says most participation and member-only areas require sign-in.
- Payment boundary: Friends of PR costs $34.95 per year and adds advanced search, a personal pattern catalogue and wishlist, bookmarks, classifieds, discounts, and other features.
- Cancellation or exit: Friends of PR recurs on its plan cycle. The account FAQ says an advance email includes cancellation instructions and also publishes an email cancellation route.
- Saved work and data: Paid tools can hold a pattern catalogue, wishlist, bookmarks, and photos, but the checked pages do not establish a complete export or post-membership retention route. Keep critical records elsewhere.

## 4. Fabric Purchase Planner

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

- Primary job: Choose materials
- Area: Materials
- For: Makers
- 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

Documenting how a pattern-based fabric quantity becomes an order length

### What the source establishes

NIST defines 1 yard as exactly 0.9144 metre. Sewing & Craft Alliance guidance ties an applicable cutting layout to the exact view, size, fabric width, and nap condition and recommends layout work when listed conditions do not fit the project.

### Know before using

The planner adds and rounds user-entered lengths; it does not create a cutting layout, infer shrinkage or matching allowances, compensate for a width change, establish usable width, or prove that the order quantity is sufficient.

## 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.
