Tester coordination for knitting pattern designers

The idea

Before a knitting or crochet pattern launches, the designer recruits 8 to 20 volunteer testers across sizes, then manages them through Instagram DMs, a Google Form, and a Discord channel. Testers ghost silently, the designer discovers at deadline that nobody finished the 2XL, and the errata feedback that was the entire point arrives scattered across three platforms. Every designer runs this circus every launch, typically six-plus times a year.

The commercial teeth: tester photos of finished objects in different sizes and yarns are the designer’s entire launch marketing, and the size-coverage feedback is what makes the pattern sellable. The milestone grid that flags ghosts early, while there is still time to recruit a replacement, is the feature no duct-taped stack provides.

Who pays

The designer pays $9 per active test and nothing between tests, which matches the episodic reality of the work and makes the first test a trivial decision. Buyers are the thousands of independent designers selling on Ravelry, Etsy, and their own sites. Distribution is where they already live: Instagram fibre-arts circles, Ravelry designer forums, and the testers themselves, who experience the product and half of whom are aspiring designers.

MVP scope

• Test setup with milestones and a public test-call application page
• Application review with size-coverage tracking
• Tester dashboard with watermarked pattern access and milestone check-ins
• Ghost-flagging progress grid for the designer
• Final photo and feedback collection packaged as an organised zip
• Skip for v1: payments to testers, pattern sales, Ravelry API integration, chat/messaging, and tester reputation scores

Build TestFlock, a pattern-testing coordination app for knit and crochet designers. Stack: Next.js (App Router), Supabase (Postgres, auth with magic links, storage), Stripe for subscriptions.

Core flow: a designer creates a test for a pattern: name, photos, sizes needed, yarn requirements, timeline with milestone dates (cast-on confirmed, halfway, finished object, photos submitted), and application questions. This generates a public test-call page the designer links from Instagram. Applicants apply without an account (email plus answers, e.g. size, yarn choice, gauge swatch photo); the designer reviews applications in a grid and accepts a balanced set across sizes, with the app showing which sizes are still uncovered.

Accepted testers get magic-link access to a tester dashboard: the pattern PDF (watermarked with the tester's email), milestone check-ins where they tick progress and leave notes or errata comments per pattern section, and final submission of photos plus a feedback form. The designer dashboard shows a grid of testers by milestone, with anyone silent past a milestone date flagged amber, then red, so ghosting surfaces in days rather than at deadline.

At test end, one click packages all final photos and feedback into a zip download organised by tester and size.

Pages: designer dashboard, test setup, public test-call page, applications review, tester dashboard, test progress grid, billing.

Pricing: $9/month per concurrently active test, free while no test is active.
