This afghan is from the pattern http://littlebirdiesecrets.blogspot.com/2009/01/quick-and-simple-crocheted-afghan.html:
It is single crochet done with a jumbo plastic crochet hook and worked with a double strand of Lion Brand Homespund yarn. I used the “Nouveau” color.
The pattern is easy but uses a lot of yarn, 8 skeins, for the size throw that it produces. The throw is pretty heavy but soft.
