For the first-timers who have perhaps worked some simplistic mysteries, Bonnie keeps the mystery going as long as possible. You may be cutting border components this first week, but you won't know it until the reveal
The next two clues may have us doing things like 400 1/2 square triangles without a clue why you are doing it. So don't expect to see a block emerging until late clues, and there are usually several blocks, so don't assume you've "got it" until very late in the game
SewBizGirl, I'm inclined to say not she won't jump the gun on Friday's clue release...but you never know.
I don't remember which year it was but she jumped the gun on the reveal, much sooner than we expected...left us thinking, Holy Cow, why couldn't I see that!
Whatever we are required to do, it will make better quilters out of us.
