How to Crochet the Daisy and Black-Eyed Susan Flower Afghan Blocks in Afghan Stitch (also called Tunisian)

NOTE (from About.com:Crochet page):

“Materials: Choose the yarn weight you prefer, according to the finished size you want. I made the examples in worsted weight yarn, using a US size J afghan hook for a finished size of 8” x 6 1/2” for each afghan block. You could also use US size G, H or I afghan hooks with worsted weight yarn. US size F afghan hook is suggested with sport weight yarn.”
