Reader Response
We have had lots of reader response to this thought-provoking article. Therefore, we are working with the author of the piece, Janet Jo Smith, to prepare a short follow-up for our November/December issue. Copyright law is a complex topic, one which we would never have space enough to present completely to our readers. But it’s also a very important topic, and one we believe all quilters need information about in order to protect their rights and respect those of other quilters. It was with this in mind that we presented Janet Jo’s answers to quilters’ most common copyright questions. Unfortunately, some readers seem to have drawn inaccurate conclusions based on the limited information presented in the article, and are feeling alarmed about situations where copyright law has little or no application. For example, vast numbers of our favorite quilt blocks and patterns have been within the public domain for years and are not encumbered by copyright law as we understand it. We’re glad the article has spurred such interest and discussion in the quilting community, and hope you’ll watch for the follow-up.

Based on the bold marks, since most of their blocks are in the public domain, I think your ok to display a quilt made with one of their patterns.
