How to Design Patterns: Step 10 - Pattern Testing

Pattern testing is one of the most important steps in designing a successful pattern, and yet, it’s often one of the most overlooked. Whether you're a designer wanting to run your first test or a maker hoping to become a tester, this post covers everything you need to know about the process, why it matters, and how to do it right.

✨ What Is Pattern Testing?

Pattern testing is when people are selected to try a pattern before it’s officially released. It’s a crucial step to:

• Test the construction

• Confirm the math works

• Ensure the fit is right (especially for garments!)

• Catch typos, unclear directions, or missing info

  
  

Testers get the pattern for free and provide detailed feedback to help the designer make the pattern the best it can be.

✨ Why Pattern Testing Matters

Even the best patterns can benefit from outside eyes. As a designer, it’s easy to write something that makes perfect sense to you, but might be super confusing to someone else. That’s where testers come in.

They help you find:

• Grammar mistakes

• Math issues

• Missing info or unclear instructions

• Fit problems (for garments)

  
  

I've had testers catch huge mistakes that saved my final pattern. They are a vital part of the process.

📣 How I Run My Testing Calls

I run testing calls for about a week. During that time, I post on my socials and email my newsletter. I include a link to a Google Form where testers apply with:

• Their email

• Instagram handle (I use this as a portfolio!)

• Skill level

• Size (if applicable)

• Agreement not to share the pattern

• Agreement to allow photo use for marketing

  
  

I usually choose 10–15 testers, especially for garments, in case someone drops out. I select testers based on skill, photos, and reliability. And I never charge for the pattern. Testers always get it for free.

If a tester finishes the feedback form, I count them as having completed the test, even if they didn’t finish the project. Feedback is everything!

🧵 Communication & Support

I run all of my tester communication through Instagram DMs, in a group chat. But other great options include Discord or Slack, especially if you want to separate topics into channels (questions, photos, updates, etc.).

I keep communication flowing by:

• Responding quickly

• Checking in regularly

• Letting testers know if I’ll be unavailable

• Being flexible and understanding (life happens!)

  
  

If someone can’t finish the test, that’s okay. They’re doing you a favor, and it’s important to treat them with grace and appreciation.

📝 Feedback: What I Look For

I provide a second Google Form just for feedback. I ask testers to share everything:

• What confused them

• What they loved

• Any grammar/spelling mistakes

• Fit issues or math errors

  
  

I read every single response. I often update pattern sections based on feedback, and sometimes I even share the updated version with the group to double-check that it’s clear!

🙋‍♀️ Want to Be a Pattern Tester?

Here’s how to stand out:

• Treat your Instagram as a portfolio. Post makes you’re proud of!

• Practice taking clear, styled photos.

• Be honest about your skill level and time commitments.

• Be ready to provide real, thoughtful feedback.

  
  

Designers don’t need perfect testers, just ones who are clear, communicative, and care.

❌ Common Designer Mistakes to Avoid

If you're a designer, here’s what NOT to do:

• Giving testers only part of the pattern

• Not responding quickly

• Unrealistically short deadlines

• Poor communication

• Forcing testers to pay if they don’t finish

  
  

Be respectful. Be organized. Be thankful. These people are giving you their time and energy, and that’s priceless.

Pattern testing can feel intimidating at first, but it’s one of the most rewarding parts of being a designer. Not only do you improve your pattern, but you also build community, learn from others, and show that you actually care about your customers’ experience.

Prioritize your testers. Treat them well. And remember: you’re not doing this alone!
