Yes, that is what I will make and use shades of gray fabrics. I have gone to JoAnn's and now have 4 yards of each shade, just to make sure I have enough. Am going to use my Accuquilt die to cut the star shapes and rotary cut the strips. Will make the stars first and make the snowball blocks to match them.
My blocks will be 12" finished and found I am making a King size quilt, the larger blocks will look nice on that size.
Thank you for the drawing and yardage information.
I feel I do not need the book at this point as it is a simple quilt, after one knows the total yardage needed.
Now to start my very large project.
Amazon has the book but really might not be helpful for making 12" finished blocks.

Thank you everyone

Gay, What a great post! Thanks.

My preference is to avoid anxiety and plan to use more than just 3 fabrics. You can always find similar fabric and I think the variety makes the quilt "one of a kind". In the past, I held my breath through a couple quilts wondering if I had enough fabric to finish. Then I decided I liked the look of a variety of fabrics anyway. Have fun with it. There are enough things to worry about--but not your quilting!

Gay, are you able to create a sample quilt using an 8x8 block setting to see if it looks odd. And maybe a 9x9 block setting to compare them.
Have never made anything bigger than a queen and am not comfortable with finding the right layout.
