Have you seen the blog Attic 24? It is awesome, especially if you crochet or knit. The colors are fabulous and the are even tutorials! Here's the ripple blanket she has completed. Isn't it beautiful? She recently posted the how-to for this and I've posted my attempt above. It took me three tries, but I really love it. I'm thinking of doing a cotton blanket/throw in the colors of this sweater of SuperBoy's.
The colors don't do it justice in the pic.
