Just be sure to be honest, don't worry about hurting someone's feelings. If the instructions aren't clear, or the measurements don't work, please say so. There are a couple of pretty famous people out there with terrible patterns, that testers just gave praise, for whatever reason - wanting to be friends with the designer? When I sent a pattern to a few friends for testing, only one gave me the honest feedback I needed - a measurement was wrong - that made a big difference. I am so grateful that she caught it before it was published on my blog.

Absolutely! I've had testers who were all about praise, and didn't find the corrections that needed to be found. And I've had a couple who have been great to find corrections and give suggestions for making the pattern better. That's the kind of testers you need!

Good Luck!
