Looking at the block you posted your first blue should have covered only the white strip and red center. Not only do I have a picture of the block in front of me but I write the number on the strip. Center is one, first light is 2, 2nd light is 3, first dark is 4, 2nd dark is 5, etc. Going in a circle like Sadiemae said.
Came up with this method because, like you, I always got lost when making log cabin blocks. Hope this is helpful. May in Jersey
