Visit bridal fairs and flower shows. While these large events are focused on selling products, they also provide demonstrations to attendees. Flower arranging is generally a topic at these demonstrations, and you can learn how to do it by watching.
Take a class. Flower arranging classes are generally held at community centers or local colleges and universities. Taking the class can be more beneficial than watching videos and demonstrations because you can ask questions to an instructor and get feedback on your arrangements.
