Okay - I found the Fons & Porter Magazine, Issue Jan/Feb 2007, page 94. If you go to www.fonsandporter.com you could probably get a back issue, but I also found that if you go the SEARCH option on this site and type in Quillow there are posting about it with patterns. They may be a little different but generally the same thing :)
I would recommend you round the corners if you make one, because it turns nicer and I always top stick after I turn so it keeps it's shape...just trials and tribulations of making so many all at once.
