According to the pattern, each pieced strip is 6 inches--5 1/2 finished--and each sashing is 3 inches--2 1/2 finished. So, one set of pieced strip plus sashing would equal 8 inches finished. You could make 11 of these sets for 88 inches in width and then add the extra sashing piece to the offside. That would make just over 90 inches in width.
After reading the pattern again and doing some figuring, I would add one set of pieced blocks (plus sashing of course) to the height. Then I think it would actually work to have 1,2,3,4,5,6,5,4,3,2,1 pieced blocks in the vertical strips. That keeps the integrity of the pattern without messing with changing the sizes of the pieced blocks. It does mean that you have to make more pieced blocks tho.
Nice pattern. Thanks for sharing.
