Thanks to all for the kind words.
I found the pattern on knittingpatterncentral.com, but it's no longer there. It came from Creative Knitting magazine. I haven't tried, but it may be somewhere on their website. I can't find the pattern right now (I may have thrown it away) It was really hard getting started as there were over 750 cast on stitches to begin with which had to be joined in the round. I had to do the join after knitting several rounds of decreases until I had a manageable number of stitches on my cable that I could make sure didn't get twisted, then go back run a small seam in that spot. But, after that, it went very fast. I love it and can't wait until next winter so I can wear it more.
