| Know before using | A suggested match is a data-based shortlist, not proof that the yarn suits the pattern or maker. Records can be incomplete or wrong, price bands are approximate, availability varies by country and seller, and shade-level matching is unavailable. YarnSub says affiliate status does not change suggestions, but equally rated matches are ordered by brand popularity. Confirm required gauge, total length, fibre behavior, construction, care, colour, dye lot, accessibility, price, availability, and seller terms, then make and assess a representative swatch before committing. | The platform is for knit and crochet rather than sewing, and a profile, application, rating, or platform listing does not prove technical competence, availability, identity, or fit for a project. Prices and plan limits can change. Define the test or edit scope, sizes, yarn, deadlines, compensation, confidentiality, intellectual property, file handling, expected feedback, and dispute process in writing before work starts. | Free access does not grant commercial reproduction or sale rights; uses beyond one personal copy must be resolved with the designer or author. Knitty says it tries to avoid errors but disclaims responsibility for pattern and technique inaccuracies. Check the live page for corrections, verify gauge and measurements, and confirm permission before any commercial use. | 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. |

| Before an account | Search a named yarn, inspect suggested substitutes, and filter by fibre and approximate price band without creating an account. | Browse public open testing calls and the provider's feature and pricing pages without signing in. | Not yet reviewed at this level. | Not yet reviewed at this level. |
| Free-account boundary | The checked core substitution route does not require an account, and the FAQ does not offer user-entered yarn records. | A free signup lets people look around, and testers participate without a platform charge. Designers and tech editors face different role boundaries. | Not yet reviewed at this level. | Not yet reviewed at this level. |
| Payment boundary | No subscription is presented for the core route. Affiliate retailer links and optional donations help fund the site; equal-rated matches are ordered by brand popularity. | Designers can pay per call or job, buy non-expiring credits, or subscribe monthly. Tech editors need a separate monthly subscription to apply for jobs. | Not yet reviewed at this level. | Not yet reviewed at this level. |
| Cancellation or exit | There is no account or recurring plan to cancel for the core route. The newsletter has a separate unsubscribe link. | The pricing page says monthly subscriptions can be canceled at any time, but it does not state when paid access ends or what happens to active tests or applications. | Not yet reviewed at this level. | Not yet reviewed at this level. |
| Saved work and data | YarnSub does not expose an API and does not accept user-entered yarn details. Use the data-issue link on a yarn page for corrections. | Designers can download pattern-test feedback as CSV or XLSX.

| Source and review | ||||
| What the source establishes | YarnSub's official FAQ says its matching software compares gauge, texture, yarn weight and density, fibre content, and fibre qualities such as drape and softness. Discontinued yarns remain searchable as starting points but are excluded from suggestions. Result filters can exclude animal, animal-derived, synthetic, or plant fibre groups and use a subjective $ to $$$$$ price indicator. The site does not accept user-entered yarn details, individual shade cards, or expose an API. Each yarn page provides a data-issue route. | Yarnpond's current pages let knit and crochet designers publish public or private testing calls, select applicants, communicate with test teams, set milestones, collect feedback, post sample-making calls, and advertise tech-editing jobs. Testers can participate without charge, while designers pay per testing or job post, use credits that the pricing page says do not expire, or use a monthly subscription that the page says can be canceled. | Knitty currently publishes web-only editorial issues containing original knitting and crochet patterns and articles. Its legal page states that patterns are free for one person's personal use, identifies each designer or author as the copyright holder, and explains that verified pattern corrections are posted in bright pink on the pattern page. | 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. |
