Tubular Cauls

I've been working on a new class and will be doing a dry run on the class in a few weeks. I recently have been researching cauls, particularly tubular cauls. They are a fun hat and over the later few months I made one. I have worn it a few times and decided that I wanted to put together a class. This will be a hands-on class that will give some basic historical information on this type of hat and examples but the main focus will be on recreating one and taking it with you. I really feel this type of class works the best for me. People want to walk away with the project at least started. I think the class will be about an hour or hour and a half tops. I'm currently working on a pattern too.
