For hat 71 I used Caron simply soft in Plum and Bernat Baby in soft lilac. The top is done with a HDC stitch twining the two yarns together. I had recently bought Crochet Edgings and Trims from Interweave books since they were having a sale and started using it for my hats. The bottom of the hat is "Grouped Relief Strands" though in the book it's all in one color. I thought it might look a bit neater separating the colors to make it stand out a bit more. I will probably make another hat using that same edging since I really like the way it turned out.
