*********DESIGNER UPDATE***********
IN THE INTRO, I HAVE LISTED 2 1/2 yd BLACK BACKGROUND, 1 1/2 yds each FABRIC A & FABRIC B and that the contrast should be between A & B. The correct instructions should read 2 1/2 yd Black Back Ground - Fabric A, 1 1/2 yds each Fabric B & C and the contrast should be between B & C
The rest of the clues have fabric A listed as the BACKGROUND as it should be and the other two colors listed as B & C, as they should be the intro is incorrect. I have now corrected that and you should download the new version when you get a chance. THE YARDAGE REMAINS THE SAME FOR THE FABRICS. CLUE #1 IS CORRECT that is what you should be using as your guide as to what fabric you have chosen for what letter.
From the pictures that I saw posted, I think you all got it right. As long as you have 2 1/2 yards of black and then 1 1/2 yds of the other two colors, you will be fine!
I am truly sorry and feel like the bottom of my coffee cup at this point!
