The center of the Mariner's Compass completed using Fat Robin Rulers.  I did a practice unit.  That was necessary step for me.  The rest went quite smoothly.  Now I am working on the next ring which is done reprising the directions for the first ring so I think I can handle it   I am contemplating switching up the outer borders using Storm at Sea or Snail's Trail blocks.  The pattern is from Quiltmania #127.
