Did you try the link to earthguild for the folkwear pattern? I ordered it from their site, granted this was a year or so ago. I can't find it on the web site now, or even the catalog they sent me so I could look up the right number & a friend has the actual pattern, but even if they no longer carry it you might love their site or catalog. Here goes
BTW, the pattern from folkwear is more a description of how to take the correct measurements than a traditional (i.e. McCalls type) pattern. Somewhere I may still have a link to different modifications that some people recommend to the folkwear pattern for use in Aikido.
