I just finished a penny rug of a moose but I can't believe that I gave it to her before I took a finished picture. Duh... but this is close to how the finished rug looked
I found the free pine cone pattern online http://planetmfiles.com/2008/12/18/free-crochet-pine-cone-pattern/
They are so easy but it works best if you use a heavy not too soft yarn. One with a bit of roughage so to speak. You will find out if you try the softer and thinner yarns that they just don't have the humph that the heavy weight yarns give them.
