I think the log cabin lends itself to a variety of processes. The trick is: Once you pick a process, stick with it and don't change midstream.
One way to control the blocks and subsequent assembly is to sew one strip to the same side of another piece. When all these are done, stack them up in the same orientation. Then figure out where the next strip needs to go. TURN the entire stack in the direction so you always sew the strip on the correct side. Repeat with the stack.
It worked for me.
