I worked this up in EQ and here are the fabric requirements.
The White and the outer bordered are 1 and 3/8ths
The Light yellow is 1/2 yard
all the rest are 1/4 yard
This is based on a 3 by 4 block setting
with a 1 and 1/2 inch inner border and a 3 inch outer border finished sizes. Cut the inner border 2 inches and the outer border 3and 1/2 inches. Cut 4 strips of binding 2 and 1/2 inches width.
I hope this helps you! Luann in CT
