Joy, I see from your other posts you are using a regular sewing machine so I would recommend either the old stitch in the ditch which works so well for sewing machines or a simple meander. I use a longarm and would normally do a baptist fan on a rail fence. A design with a curving flow nearly always works well on a block to block design with simple squares or rectangles. The curve of the quilting gives the piece a softer look of movement. Happy stitching.
