Rosy, I am starting a queen size lone star next week...all hot pink/black/white. I did a very small one recently, and am looking forward to doing it in large scale.
I think I have overcome my issues with the Y seams, and the joining of the center. I THINK!! :-)
I will post mine when I do it...and I'll probably be hollering for help!!
I love the colors in the one you are working on...they do have a great eye for pattern and color.
