Thank you for the very kind responses! The first time I tried this block at quilt camp I was so pleased with myself ....until I measured it out and it was much smaller than the required size!! I had been so careful about that quarter inch seam. I couldn't figure out where I had gone wrong. Another quilter came over to help me asked me what ruler I had used, when I showed her ... It turns out I had used a set of rulers that was different than a traditional ruler. Once I used my own rulers at home the block came out perfect. As I said in my post now I'm hooked on any kind of star block!!
Thank you again!
