Ps 150

I made this wall hanging, but have no idea how to quilt it, considering the beautiful gold swirls throughout the main, green fabric. I really think the fabric is so pretty and don't want to cover up the beautiful design too much. I saw this, made with the same fabrics, at my LQS, but they did not quilt it at all. I don't think I want to do that, though, because wall hangings tend to sag if they're not quilted enough. What do you think?
