The yarn is Caron Tea Cakes. I love that this yarn is variegated and that the colors blend from one to another as you crochet so that when you're done you have a gorgeous, multicolored blanket without many ends to darn in; that's what I call a win-win.
Like I said, the pattern for this blanket was on the yarn label. It was a simple pattern - easy to work on while watching Game of Thrones - and I even learned a new-to-me trick. Because it is a rectangular blanket, you start by making a chain and then crochet your groups of three around the chain. Having the solid chain in the center keeps the design straight. I've often made granny square blankets and the center has gone off and not been straight at all, even after blocking, which really bothers me. Starting with a chain adds some stability, its' a little tip I'll have to remember.
