How to write a call for pattern testers that gets the right applicants
Templates and examples for writing a sewing pattern tester call. What to include, what to leave out, and how to filter for reliable testers before they even apply.
A call for pattern testers does two jobs at once. It attracts people who want to test your pattern, and it filters out people who shouldn't. Most calls do the first job and forget the second, which is why so many designers end up with 80 applicants and only 6 they'd actually pick.
This is the structure that works.
The five things every tester call needs
- What you're testing. Pattern name, garment type, fabric requirements, difficulty level.
- Who it's for. Size range, which sizes you most need to fill, any specific body types you're prioritizing.
- The timeline. Application close date, when testers will hear back, test window dates, feedback deadline.
- What you'll ask of them. A finished garment, written feedback, at least two photos, social posts, and whether you'll re-use their photos.
- The non-negotiables. What happens if they miss the deadline, ghost, or don't deliver photos. Be polite, be clear.
A template you can copy
Here's a call you can adapt in five minutes:
Pattern testers wanted — [Pattern Name], a [garment type] in sizes [X–Y]. Testing runs [Date] to [Date]. I'm especially looking for testers in sizes [X, Y, Z].
You'll receive the pattern and tester brief on [Date]. In return I'll ask for: a finished garment, structured feedback by [Date], and at least two photos I can use in the launch (with credit). If you can't hit the deadline, please don't apply for this round — there'll be another one soon.
Apply here: [link]. Applications close [Date].
What to leave out
- Vague language like "fun project" or "casual round" — it lowers the seriousness bar.
- Open-ended questions in the post itself. Save those for the application form.
- "Anyone can apply!" if you actually only want experienced testers — say so.
Where to post it
The full breakdown is in our guide to finding pattern testers, but the short version: your own audience first (newsletter, Instagram stories), then niche pattern-testing Facebook groups and Discord servers, then your past-tester directory.
A well-written call gets you fewer but better applicants — which means less time sorting them and a more reliable round.
