Magic Potholder pattern by the Crochet Geek.  This pattern can easily be found on The Crochet Geek's website or on Ravelry.com.  I love it.  You start off with a chain, up one side and down the other and continue.  It eventually begins to fold itself on two ends, close up the seam and voila!  you have a finished, professional looking potholder that is stylish and effective!  Love this pattern.  Oh, and best of all the pattern is FREE!
