The other day a friend and I were looking through an antique store and the clerk was crocheting a granny ripple afghan. I commented to her that I had been going to try to learn that stitch. She asked me if I wanted her to make a copy of the directions. I said yes, came home and sat down to learn it. I'm using yarn I already have so it would not be my first color choice but I like it anyway. The first two rows I had to pay close attention to the directions and then after the third row I was off. Its a neat stitch and would make a great scrap afghan.
I will try to remember to post pictures once its done.
