this is a really great pattern you have there especially if using lush fabric in the middle squares. I have now done 2 kings and one thing i really like about the first one is that the inner border (sashing) fell in the exact right spot. i also have a huge drop and the pattern i used was king but about 15" too short on both sides! i wound up getting very creative in making it wider but it worked really well. I could see you floating another row of the squares on the sides even if not the same size as your middle. i typically like things calming and serene in a master...which can still be scrappy depending on the fabrics used.
