hmmmm, you could do some diagonal lines. I would go from one corner or near the corner through the center of the quilt and through the center of the blocks. then another line on one side of that line maybe one inch or two away and continue taht way up to or down to a corner. then turn your quilt and make one straight line from the center or near that through the blocks down to the opposite corner and fill in on either side of that to the edges of the quilt. I wish i could fine a good photo of one i did that way but can't right now. looks good. gives a lot of interest and fills the quilt with stitching needed.sort of like this but without the lines going bottom left to upper right on the lower half of the quilt and the upper half not having the crossing lines either.
