### 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. 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

### 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.

## 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. QuiltMap

### Best for

Finding quilt-material sellers and adjacent quilting services by country or map

### What the source establishes

QuiltMap describes free public search and free basic listings, community submissions and claims, and country routes covering North America, Europe, Japan, South Korea, and Australia.

### Know before using

Coverage is quilting-specific and uneven by country; businesses can pay for enhanced features, and community or owner updates do not verify inventory, service quality, hours, or availability.

## 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.
