Another fabulous way to do a Lone Star (although limited to a 4x4 tp 6x6 grid) is using the Quiltsmart interfacing. It's quite ingenious, NO diamonds. Nada, not a one. And as long as you read the directions BEFORE you use it, you don't have to worry about any bias.
I've used it quite a few times, and it is most certainly worth the price in time and aggravation.
They also have mini size. Plus, if you get adventurous and really understand the concept, you could combine some of the foundations for larger stars.
I see that now they're selling it by the panel.
NAYY.

I just wanted to add that even if you do it the Quiltsmart way, Jan Krentz's Lone Star book is worth every penny. Her directions and hints for settings are really helpful and spot on.
