I love star blocks. Any star block. All star blocks. I'll have to add this one to my repertoire.
This block actually gave me a little trouble. My "scant 1/4 inch" seam was a little too scant and then the block was a little too big. Trimming to 13 inches would have trimmed right into the star points. Grr. A swear word or two, a quick date with my seam ripper, and a less scanty scant 1/4, and we were in business.
