My frame is a Grace Mini Pinn with 3 rails, so yes, I turn. Am thinking, it's no big deal, turning them back, or forward, just haven't tried quilting a quilt this way yet. Seen alot that Chrisma & others on here have done, like this, so am curious. Thanks for your input, & yes, one color in bobbin, for backside. So I would just have to change the top thread the one time, I am thinking...
