I understand Randy spoke about it in his Convergence workshop in 2002; we've seen him speak about it on the Craft in America video. (Did he smirk when he said "run of the mill"?) But he didn't touch the subject in our workshop a year ago.
It's one of the those questions that haunt me from time to time, this time over at Curious Weaver's blog. It's too bad Kelly did not leave a link to her blog or web site if she has any. It would have been interesting to read her thought further as well.
