Good morning, all.
Elisabrat - you won't need your E nd F fabrics until clue 5
Sauki - as you had read in previous comments, you need contrast and not a lot of similar backgrounds (i.e. your white background fabricss) And also we know that the E and F fabrics will draw the eye into the quilt and should have good contrast between the two and with the other fabrics. That said, and I apologize if I was too brutal - please try again as I feel your greens are too similar in tone and nothing will stand out in your quilt.
Jennify - those are beautiful blues! May I suggest on the C-D that C is darker than D as mentioned before, so when you shop for a new D please reconsider not shopping for a navy because I think it will betract from the beautiy of your blue prints. Keep your favorite F and maybe when you are shopping, a new E with a bit more contrast to the F will pop out at you. If not, your E will work.
