| Best for | Turning an inherited or proposed garment tolerance into a controlled POM method, capability study, decision boundary, inspection rule, and change record | Researching loom-ready weaving structures and drafts | Searching current and out-of-print sewing patterns | Building a substitution shortlist for a discontinued or unavailable yarn before checking quantity, availability, and a representative swatch |
| Know before using | The record does not supply universal POM values, validate fit across a population, prove process capability, choose a statistical study or sampling plan, reproduce licensed standards, or replace qualified technical, fit, quality, statistical, safety, compliance, and legal review. | 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. | 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. | 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. |

| Access scope | Not yet reviewed at this level. | Weaver deciding whether viewing a draft is enough or a working WIF file and editing tools are required. | Sewer searching pattern records or organizing patterns, projects, fabric, notions, and private files. | Maker comparing a replacement for a named yarn before buying. |
| Before an account | Not yet reviewed at this level. | Browse the Ralph Griswold archive, download archive documents, and view draft drawdowns without a paid subscription. | Browse the pattern database, guide, designers, publications, and public community areas without creating an account. | Search a named yarn, inspect suggested substitutes, and filter by fibre and approximate price band without creating an account. |
| Free-account boundary | Not yet reviewed at this level. | A free basic account adds clipboards. Full drafts, working files, and browser drafting tools remain outside the free account. | A free account needs no card and supports a stash, wishlist, projects, reviews, and personal organization. | The checked core substitution route does not require an account, and the FAQ does not offer user-entered yarn records. |
| Payment boundary | Not yet reviewed at this level. | A monthly or annual recurring subscription unlocks full drafts, WIF downloads, and browser drafting and editing tools. | Plus adds PDF pattern storage, collections, saved searches, bulk editing, and other workflow features on monthly or annual billing. | 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. |
| Cancellation or exit | Not yet reviewed at this level. | 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. | Cancel through an in-account link. Paid features remain through the current billing cycle, then the account returns to free features. | There is no account or recurring plan to cancel for the core route. The newsletter has a separate unsubscribe link. |
| Saved work and data | Not yet reviewed at this level. | 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. | 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. | 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. |
| Source and review | ||||
| What the source establishes | The guide cites current ISO, AATCC, and NIST sources for body and garment measurement boundaries, textile conditioning, dimensional-change testing, repeatability and reproducibility, and AQL-indexed sampling, while requiring the live product owner to set rather than inherit numerical tolerances. | 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. | 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. | 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. |
