Seems a lot of patterns have errors, but what really gets me is the pattern makers/publishers usually know about the error. Most patterns have a disclaimer saying "not responsible". While making a quilt top, got to final stages and discovered major error, contacted company that published and made them refund me for fabric and some of my time. The book did not have a disclaimer therefore, I could get reimbursed. What really upset me was the book was reprinted with the same error even though it was known by pattern maker/publisher.
