I have been fortunate to have such good mentors. Their one common element is that they are genuinely nice people with a ready smile. I love to walk into a quilt shop with a class going on and hear all the chatter and laughter. So, my advise would be to relax and have fun. Model for you students the joy of working side by side, the satifaction of doing a new skill for the first time, and the frustration of making the same mistake 3 times in a row. This is a beginning quilt class, if you can share the joy of quilting, they will be happy to know that there is a life-time of learning ahead.
