I have put together a quick paper piecing pattern for the Mariner's compass block that I used for Amy's pillow since some of you were interested in it.
I modified the typical Mariner's compass a bit by adding more points to the stars in the back.
Download link here for the block pattern pieces.
Each Pattern only makes 1/4 of the entire block. You will need to print out the pattern four times to get each of the 4 block sections to complete the entire Mariner's compass. Make sure your printer is set to print at 100% or 'No Scaling'.
All seam allowances are 1/4".
Here is a schematic of the finished block. The finished block is 12".

For the pillow, I rotated the star just because I liked the look of it that way, but you can make it however you like.
