I am always searching for new things, especially yarny things, and I found another awesome blog. Yarn Muse. Anyhow, I know you have seen those fabulous pics of the complicated layered scale looking crochet technique... well, she figured it out! And she explains it for free. I will admit it's a pretty complicated stitch, but don't give up. I played around with it and used my intuition and was able to get it in about 15 minutes. I do see where she later updated the instructions and added videos for help. You should check it out!!
