Cool thread!! I'll becoming back here a few times to read all the tips! I too, keep a journal or notebook with the quilts I work on. It's to help me with the calculations and patterns, etc. I also recently heard of the sticky roller idea and now have one dedicated to my sewing room.
I think a tip I could share is: don't worry if your quilt isn't perfect. I look at is as a personal challenge - maybe the seams on this particular quilt don't line up, but I will learn how to do better next time. Like a golfer - they really play against their own scores and not really against others.
