This post may seem scattered, because we learned things as we went - and this post will probably look the same way. However, we hope you can learn from other people's mistakes experiences. It will mix your general instructions with our tips - because ultimately we winged it {as much as a control freak can "wing" anything}. Here goes nothin'! *Sorry for all of the words and less pictures, these are more brain tricks and tips and unfortunately, we couldn't snap pictures from inside there!
Patterns and Execution
Tip #1: Turn the last board in the row around so the groove is up next to the groove {length wise}, mark where the cut should go to make it shorter {should light up with the board you lay immediately prior to this step - make sure to leave room for the gap!}, and cut there. Instead of measuring, marking, etc. we found this method to end up in an extremely low error rate and made the process go much faster. The majority of the time, if there was a "miscut", we were usually making it too long instead of too short which meant we could correct the error. Yardsticks really help when you made an ut-oh cut. {If you would like pictures or further explanation of this, just let us know in the comments, after much searching for a picture, we couldn't find one. But we could definitely stage the situation for you if you would like!}
