I just took a 3 hour class over the weekend from a great instructor. She was patient, helpful and PREPARED. She had printed instructions and little pre-cut sample in each stage with instructions written on them. Plus a pre-cut kit that we could work on. Then she had completed quilts to show the different concepts.
She knew how to demo. She did not hard sell but each of us spent money because she explained why you would want to have this or that.
This is the second class I have taken from her which says alot since I have to drive over an hour and a half to get there and I pass a dozen other LQS plus a Joann's, Hobby Lobby and Hancocks. Plus the class was on a weekend.
