The simple answer is, as many as it takes. We don’t release patterns until we are absolutely certain they are ready for sale. We run internal testing among the members of our team before approaching a limited number of testers in each size group for pretesting. Once pretesting is over, we run one large test of 30-40 testers. If we feel there are still issues with the pattern, an additional round of testing will be done. Testers are often required to sew the pattern multiple times in each testing round.

It is serious work to be a pattern tester. You are often required to sew multiple versions of a pattern and must have a meticulous eye. You also must be able to communicate fit issues to the designer and meet tight deadlines.

Every single pattern we release is fully tested in all size ranges. We use home seamstresses of all skill sets to ensure that our patterns can be made easily at home with minimal fit alterations. One pattern often goes through multiple rounds of testing by 30-40 testers to ensure it is ready for sale. This also includes free patterns. We put as much love into those as we would a pattern we would list for sale.
