No, I don't get a share of the profits, but I want to recommend this book, because I think it is excellent:
Mariner's Compass Quilts: Setting a New Course New Process, New Patterns, New Projects
Author: Judy Mathieson
I just did my first ever Mariner's Compass (sorry no pic at this time). It is 15" in a 17" block. It has 16 points, all split. No, the points are not perfect, but it certainly meets the galloping horse test.
I think the instructions are great and the patterns are good too.
Oh, and her description of how to block the block took the cone right out of it :-)
