This has been a very interesting topic as I have been quilting since the 1980's ad the changes I have seen are amazing, gone are the days when we used scissors and card board templates, women got together to sew together and exchange patterns and what relaxing fun we had then greed came in , designer fabric, patterns copyrighted, against the law to buy one pattern to share with a group, When I started taking classes it was from teaches doing demos from their book with photo copied work then if we wanted the book we bought an autographed copy now everything in on the internet so we no longer need books, patterns or classes and quilting has turned into a solitary thing rather than group also now micowave quilting gotta get her done. we use to be a group all winter on a project
