I'm glad so many of you enjoyed my granny ripple. A few people had questions and just incase your like me and forget to check comments... I'll do them here.
Freda: I bought one skein of each color I used. I used 8 different colors, so 8 skeins. But I doubt I even used half of 7 of them. I used more of the teal since that was my border color. For an adult blanket, I'd suggest at least 3 of each color you are wanting to do. Just to be on the safe side!
Laura: Oh I love using the Simply soft. I'm actually in the process of doing wholesale yarns and carrying the simply soft. About the color changes, I just left a tail about 3 inches long after each color change and then did my border over them, covering them up as I went.
