One way to do a quick check on the fabric requirements is to do the math. The suggested fabric for your pattern was 1 1/8 of 6 fabrics. That is a total of 243 inches. With 40 usable inches, that much fabric should give you a maximum of 9,720 square inches (less after accounting for seam allowances).
A standard queen size quilt is 90 by 108 inches. Which equals 9,720 square inches. This, if anything, ore fabric will be needed to complete a single queen quilt top.
