Journey of Quilting

Help!

Remember this quilt?

Courtesy of staying up until 1 AM this morning, this quilt top is almost done and I'm trying to figure out how to quilt it. This is the biggest quilt I will have machine quilted... it's approximately 60 x 72. There are other blocks mixed in that have larger amounts of white sashing around them but I don't have a good picture of the final top yet so just use your great imaginations!
How would you quilt this quilt? I have done a random stippling on my last two quilts and I am comfortable with that technique. But then I'm always looking for new ways to branch out. I like the organic line quilting like this so I'm really considering this method as well.
What do ya'll think? And I'm open to other ideas as well... Thanks!!
