Very pretty churn dash blocks. Most traditional hand quilting of old blocks I've seen is usually 1/4inch inside the seam lines or cross hatching. Are you planning to hand quilt it? If you are going to machine quilt it, I think I might try a traditional pattern like Baptist Fans or Orange Peel? I love Baptist Fans on a quilt but there is no way I would ever have the patience to hand quilt them. I have seen both a machine pattern for them and someone doing them freehand on the net.
