# Stitch Authority resource comparison Generated: 2026-07-29T13:43:58.202Z Comparison: 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. ## 1. India Basic Pattern Development Textbook Permanent record: Source page: - Primary job: Find patterns & fit - Area: Patterns & fit - For: Both - Location or jurisdiction: India ยท South Asia - Access: Free download - Format: Reference - Source type: Government guidance - Linked page reviewed: 2026-07-16 - Next review due: 2026-10-14 ### Best for Following a structured classroom introduction to womenswear block development, muslin test fitting, fit correction, and basic flat-pattern manipulation ### What the source establishes CBSE's official publication index links the Class XII Fashion Studies textbook. Its Basic Pattern Development chapter covers body and dress-form measurement, size relationships, patternmaking tools and terms, fit and balance, muslin test fitting, block correction, bodice, sleeve and skirt blocks, seam allowances, grain lines, notches, necklines, collars, and dart manipulation. The stated learning outcomes include developing blocks from charts and body measurements, testing fit, correcting the pattern, and developing simple designs from basic blocks. ### Know before using This is a classroom textbook with particular womenswear exercises, charts, figures, terminology, units, and drafting methods. It is not a universal body, block, grading, or sizing system; current industry certification; or proof of fit for an individual wearer or product. Some content and examples predate the current review. Verify the intended body data, measurement protocol, ease, material, seam and construction rules, accessibility, current curriculum status, and representative sewn fit independently. ## 2. Swatch-to-Area Yarn Estimator Permanent record: Source page: - 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. ## 3. YarnSub Permanent record: Source page: - Primary job: Choose materials - Area: Yarn - For: Makers - Location or jurisdiction: Global - Access: Open access - Format: Reference - Source type: First-party platform - Linked page reviewed: 2026-07-28 - Next review due: 2027-01-24 ### Best for Building a substitution shortlist for a discontinued or unavailable yarn before checking quantity, availability, and a representative swatch ### 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. ### 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. ### Account, payment, and exit - Access scope: Maker comparing a replacement for a named yarn before buying. - Before an account: Search a named yarn, inspect suggested substitutes, and filter by fibre and approximate price band without creating an account. - Free-account boundary: The checked core substitution route does not require an account, and the FAQ does not offer user-entered yarn records. - 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. - Cancellation or exit: There is no account or recurring plan to cancel for the core route. The newsletter has a separate unsubscribe link. - 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. ## 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.
