There are a number of sources available to someone wanting to learn loom weaving, such as the sites for Woolery, Craftsy and Village Spinning and Weaving. Woolery, for example, offers instruction videos on DVD for people at different levels of weaving.
Craftsy also offers video instruction on DVD. The DVD options can be very handy for people who are just learning because they can play and access the instructional material at any time, even if they are not near an Internet connection. As long as they have something to play DVDs they can watch the videos. Village Spinning and Weaving offers a large selection of videos on both VHS and DVD, which covers a wide variety of projects and skill levels.
