I teach quilting weekly and the most important thing is to plan ahead and get organized so that there are no last minute "oops". Decide on the skill or techniques that you are demonstrating, make some samples, gather all of your supplies well ahead of time (check them off from a list)pack your needed things in an easily accessible bin or rubbermaid container, go a little early to get set up and relax. This will be interesting and you will be sharing great skills with others who will appreciate your efforts. Adults are usually eager students wanting to learn. You will probably learn something too even if it is not about quilting. As for your priest, send him to Canada as our charge is searching for a minister!
