Have you thought about using another MSQ tutorial- how about Jenny's "Diamond Dash" pattern, it also uses the Layer cake or yardage cut 10"x5" and snowballed on the end to make a diamond. I too just finished or need about 12-14 inches to finish hand sewing the binding on a Quilt for DD's Christmas quilt using the same "Illusion" pattern that you used here what a fun quilt to make, my blocks are really bright!. Now I just have to finish DS's Star Wars" quilt for his Christmas Quilt.
