Belfry - you will need borders to get to the size you are looking to make.
Adamae, happytab and carrot -- welcome to our new passengers on the Mystery Train
Francie, we all sympathize -- and none of us OCDers can understand those who need to finish A before starting B
Sulabug, welcome back. As to the 4" squares, can't see why not, but you will have to adjust everything else as you go along. Don't cut anything until you get to that week's clue, and I think you will be able to figure out how to cut the other pieces as we go along.
Sustraley -- thank you thankyou, you are so sweet.
OOOOOO coopah - what happened - thought you were along for this ride too -- we will miss you.
