I bought a quilt book by a well known quilt designer. In the book it said email for permission for one quilt to be used in a workshop. I emailed for permission to use the pattern in free workshop for 10 people. I never go a response. I emailed every week for six weeks, even emailed the publisher. Never got a response. I thought about leaving a comment on her blog but decided I wasn't going to beg. I sent the last email saying since she did not say no I was going to assume the answer was yes. I used the pattern for the workshop. Even sent pictures of the finished blocks to her website. Never heard a word.
