So Who Didn't Follow Directions?

As the list of things still needing attention in The Pumpkin Project slowly dwindles, I begin to daydream about fall book signings with my finally completed book in hand. Then I needed a picture for an introductory comment in the book.
That's when I realized I had a problem.
One of the first directions in The Pumpkin Project is to get a notebook to keep records of all the Investigations. Step 1 of every Investigation says to open this Journal and write the number of the Investigation and date in it.
Guess who has no such Journal?
You are right. I did the Investigations on pieces of paper now scattered in various piles of Pumpkin Project related notes. Not in a Journal.
And I need this Journal. First it will be a nice picture for the introductory directions. Next it will sit on my signing display along with a fake pumpkin. [Real ones don't do well for such events but perhaps I can sneak in some pumpkin cookies.]
So I bought a new notebook. I created some stickers [Try finding pumpkin stickers in July!] and decorated it. Now I am going through each Investigation and writing them in the Journal.
That is, I was until I got to Investigation 7. I know I did it. I have the pictures to prove it. Now, which pile contains the paper with the measurements on it?
