PROMPT 1 OF 3

Build a web app called Pattern Tester Hub. Designers sign up and create a test call with pattern name, craft type, sizes needed, number of testers, start and end dates and requirements. Publish a public application page.

PROMPT 2 OF 3

Testers apply with name, size they will make, experience level and social handle. Designers pick testers per size. Selected testers get a private page to download the draft pattern and submit feedback: errata found with page and row, fit notes, time taken and progress photos.
