If you are making the Beach Balls quilt, you may need an extra 1/4 yard of the white fabric, depending on how you cut.  It you completely open up the strips when cutting (rather than having them folded so they are 22" wide), you will make better use of the fabric and have less waste at the fold.  If you use this method to cut, the fabric requiremends in the pattern will be enough.

 

Correction to the White Diamonds quilt:

From the Fat Quarters cut:  2 - 8" x 22" strips. (not 8 1/2" x 22")
