This is an excerpt from my second DVD, which teaches seven chainmail weaves including Dragonscale. The mini-DVD came about when I taught a class based on Dragonscale. This weave has a (somewhat well-deserved) reputation for being tricky, so I decided to provide my students with a pause-and-rewind Spider that they could take home after the class. And since I was printing them for my students anyway? I made a pile of extras.
If you want to learn a whole bunch of weaves? Buy the main DVDs.
If you only need pointers for Dragonscale? Buy this DVD.
