What batting will you be using? How large are the blocks? You will want to quilt close enough to hold the batting in place for years to come with a quilt as adorable as yours. Since I normally use cotton batting which needs to be quilted about every 4 inches, I would SID the sashings,the borders, around the dragons and also SID stitch on the dragons themselves. Then I really like the idea of flames in the background and on the borders. The SID around and on the dragons will really make them pop and if the backing is a fabric that "reads" as a solid the back will be beautiful also.
