There are some terrific online classes started here:
These are perfect for newbies or for people wanting to learn new techniques and includes a RH twill class from Amelia Garripolli, as well as warping with a paddle and other useful warping techniques, using a McMorran Balance, and a crash course for newbies on reading a draft. You can even get a crash course in how to attend an interactive Cyber Weaving class. Feedback from people who have done this already is good, and they are timed so people from Europe and most of Australiasia can attend too! Places are limited.
