This pattern is found in “A Year of Afghans”, Book 5, Page 132,
  a Leisure Arts publication.  The afghan required 31 1/2 ozs
  of worsted weight yarn, crochet hook size H, measured 46”x 60”.
  This was a fast and easy afghan to crochet, finished in
  a beautiful  lace design, and very economical as I only had
  to buy two skeins ( 16 ozs each) of yarn.
