Meander sounds good. Do you have some experience with FMQ? If not, definitely create practice swatches before tackling a quilt like this.
To keep the quilting soft, use a finer thread. I once close-stippled a doll quilt with regular thread; it came out stiff as a board! On my domestic machine, I now like Aurifil 50wt 2-ply cottong for quilting. It is a fine thread and does not create much lint. On my midarm frame, I use Glide 60wt polyester thread.
