I finished 5 blocks, one correctly and 4 incorrect, then mixed them up and showed them to several people to see if they could find the good one.....nobody could tell the difference without studying the blocks, and a couple couldn't see any wrong at all....so I have decided to just continue with the blocks as is, adding the rest of the red logs....if the blocks were constructed with light logs and dark logs, I would never question about fixing them, but since they are all red logs surrounding a cream center, the error is hard to see...I will post a pic when done.
