January Log Cabin - 6. Layout

OK - so if you are like me, you too have sewn 18 of these blocks in January.  Crazy I know, but when I see a dead horse I like to flog it!

Here are some photos of my scrap 16 blocks.  I have to decide how to put these together now, and what sort of arrangement or effect I'm going for.  These 4 are not your only options - there are many ways you can put them together.
Let me know what you think I should go for.
