damaquilts

I have finally almost finished my garden trellis quilt. I had to do a simple X design on the center with a serpentine stitch , I wanted to do something prettier but couldn't manage . Anyway I stitched around the outside of the applique on the border. I know it needs more quilting but am stumped as to what to do. I thought about echo but that would put more quilting on the border than on the middle and I didn't think wide echo would look all that well. I also thought about straight lines or cross hatching.. So any other suggestions or what do you think about the cross hatching or straight lines.
