I too, was looking for a pattern (free of course) for the folded star pot holder. Well I found this one:

and the best thing is that it is in PDF format. Just scroll down a little way & she has the link to the PDF. She gives great instructions. I am making some of the folded star christmas ornaments for christmas & plan to do some of these pot holders next. Hope this helps someone.
