If I recall correctly, the blocks were all the same. I remember having the pieces all cut and lined up, stacks and stacks of each length and then neutral and the red block. I made mine scrappy.
I started out sewing the red to the neutral, and then added the correct length of neutral on that end, and then the correct length of print on the other.
Then when I had all my "logs" sewing, I started putting them together in the log cabin pattern. The different is that you only sew two sides instead of going around on all four. Starting with a 4 patch neutral and the added longer and longer strips until you end with the longest print strip.
