simple stitches & warm wool yarn.  i started the afghan while living with my inlaws.  at first it was intended to mimic the chunky monochrome shawls for sale for prices beyond my means in la garconne.  while i give a nod of respect to their styling, i figured there was no intellectual patent on the granny square, and i needed something to do to keep my hands busy and kill time.  after we moved into our own apartment i transitioned it to the grey afghan it is today.
